The Sore That Appears in Bed: Pressure Injuries
Your mom can't move on her own. And her skin, pressed against the bed hour after hour, is slowly losing its blood supply… in silence. A pressure injury doesn't appear "because of age": it forms where the bone presses, and it almost always warns you before it opens. In two minutes: how it forms, the first sign on the skin, what actually helps at home — with the honest nuance about "every two hours" — and when to call that same day.

What is a pressure injury?
It's the sore that forms where the body presses the skin against the bed or a chair for too long. Think of the body's weight as a hand pressing on the same spot, hour after hour: bone on the inside, bed on the outside. That constant pressure cuts off the blood supply to the area, and without blood the tissue is damaged or dies. And it starts on the inside: the muscle under the skin suffers first, before anything shows on the surface.
It forms where the bone sits closest to the skin: the heels, the lower back (where the tailbone is), the hips — the elbows and the back of the head, too. It's almost always the same places, which means they can be checked. People who are in bed, use a wheelchair, or can't change position on their own are the ones at risk — and many of them can't feel the damage, or can't tell you.
The skin warns you: the first sign
Before it opens, the skin speaks. The first sign is a reddened area that doesn't fade: you press gently with a finger, let go, and the color doesn't come back the way it does on the rest of the skin — it stays red. On darker skin the sign looks different: look for an area that's darker than the skin around it, or that feels warm, soft, or firm to the touch, compared with the other side of the body.
The check is simple: every day, while bathing or dressing the person you care for, look at the bony areas — heels, lower back, hips. It takes ten seconds, and it's the moment when the sore can still be stopped.
How to prevent it at home
What helps is in your hands, and it comes down to three habits: move, check, call.
- Reposition on a plan. The current clinical guideline (the International Guideline for pressure injuries, 4th edition, by EPUAP, NPIAP and PPPIA) suggests repositioning in general every 2 to 3 hours for most people at risk, adjusting to how their skin responds and the surface they're lying on — and not routinely stretching it to 5 or 6 hours "so she can rest." There's no single clock for everyone: the plan is agreed with her care team. And no mattress, however good, replaces repositioning.
- Seated, relieve the pressure every hour. If the person spends the day in a chair or wheelchair and can't move on their own, they need help changing position often: the caregiver reference is every hour.
- Position to offload the points. On her side, tilted at about 30 degrees with pillows, never lying on an area that's already reddened. Heels off the bed entirely: "floating," with a soft support under the calves.
- Lift, don't drag. When you move her, lift her with a sheet or with a second person's help: dragging hurts the skin with friction.
- Clean, dry skin. Moisture weakens skin. And make sure she eats enough — calories and protein — and drinks water: skin also defends itself from the inside.
When to see a specialist
Some signs can't wait for the next appointment. Get a professional assessment that same day if you see an open wound, black or purple skin, drainage with a bad smell, or a fever. And if a wound hasn't improved in two weeks, that's not for waiting either: a sore that has already opened isn't treated at home — a specialist needs to assess it.
At Red de Salud Hispana we connect you with a specialist who speaks your language, in California: contact a specialist →. That's our mission: clear information for caring at home, and the bridge to a professional when the skin warned you and it didn't heal.
Ask her care team this
“How often should we reposition her, given her skin and her surface — and which areas should I check every day?”
If you remember one thing, make it this: move, check, call.
Frequently asked questions
What is a pressure injury?
It's the sore that forms where bone presses skin against the bed or a chair for too long: constant pressure cuts off the blood supply and the tissue is damaged, starting on the inside. It appears mainly on the heels, the lower back, and the hips, in people who are in bed, use a wheelchair, or can't change position on their own.
How often should a person in bed be repositioned?
The current clinical guideline (International Guideline, 4th edition, EPUAP/NPIAP/PPPIA) suggests in general every 2 to 3 hours for most people at risk, if the surface spreads the pressure well, adjusting to how the skin responds — and not routinely stretching it to 4, 5 or 6 hours. It's not one rule for everyone: the frequency is agreed with the care team, based on each person's skin and surface.
What is the first sign on the skin?
A reddened area that doesn't fade when you press gently and let go: the color doesn't come back the way it does on the rest of the skin. On darker skin, look for an area that's darker than the skin around it, or that feels warm, soft, or firm to the touch. If you see it, tell her health care provider that same day.
When should you see a specialist?
When the wound has already opened, the skin looks black or purple, there's drainage with a bad smell, or there's a fever — that gets assessed the same day. And also if a wound hasn't improved in two weeks. An open sore isn't treated at home: a specialist needs to assess it.

Your mom can't move on her own. And her skin, pressed against the bed hour after hour, is slowly losing its blood supply… in silence.
That's how a pressure injury — a bedsore — begins: where bone presses skin against the bed for too long, blood stops arriving, and the tissue can be damaged or die. And because many of these loved ones can't feel it, or can't tell you, nobody notices… until the skin has already opened.
It forms where the bone sits closest to the skin: the heels, the lower back, the hips — the elbows and the back of the head, too. It's almost always the same places. Which means they can be checked.
What does help — and it's in your hands: change her position on a plan — on her side, tilted with pillows, heels floating off the bed — and when you move her, lift, don't drag, so her skin isn't hurt. And every day, while bathing or dressing her, check those areas and keep her skin clean and dry.
The honest nuance: there is no single 'every two hours' that fits everyone. The current clinical guideline says: in general, reposition every two to three hours if the surface she's lying on spreads the pressure well, adjusting to how her skin responds — and don't stretch it to five or six hours 'so she can rest.' And no mattress, however good, replaces repositioning. The plan is agreed with her care team.
If a check shows an area that's reddened or changed in color, warm, hard or spongy, or skin starting to break open: don't wait for the next appointment. Tell her health care provider that same day. A sore that has already opened isn't treated at home: a specialist needs to assess it.
Keep this: move, check, call. Ask her team: 'How often should we reposition her, given her skin and her surface — and which areas should I check every day?' At Red de Salud Hispana you'll find the complete chronic wounds guide, and we can connect you with a specialist who speaks your language. No obligation. We're not doctors. See you tomorrow.
