What is the remedy to 'bedsore'?

A bed sore is caused from pressure on one particular part of the body. Turn the person so that area is not receiving any pressure , keep the area clean and watch carefully for infection. There will be a reduction in the circulation so it is a good idea to rub around the area to increase circulation.
Depends on the age of the person and their general health and how good you are at massage to bring the circulation back as to how long it will take for the sore to heal.

I have never used any creams on a bed sore unless there was infection... Cleanliness and massage.
You have your work cut out for you for a while.

first go to ur family doctor and say about the problem, frequency of bedsore is it everyday or rarely, take the treatment as nearly as possible

main therapy is keeping the area off pressures, because thats the reason for it.
so change position every 2 hours.
keep area clean and open and apply antiseptics.
see to it than it wont catch flies.
if ther is pus, add antibiotics.
see to it that there are no creases to bed on which the part lies.
You can put water cushions under bony sites so that pressure is minimised.

If the bedsores are really bad ask your docor ans they can prescibe something. They did that for my dad when he was really bad they gave him a prescription.

change of position keep the persons weight off the bedsore using pillows and different soft things to position the person so the bed sore is not in contact with the bed or chair.
if the sore is open then you will need a medical cream to treat and its best to ask a doctor for what one to get. the person should be moved at least every two hours so new sores don't develop . a minor bed sore can be treated at home very well as can more severe ones but since you didn't know how to treat them you should have a nurse or doctor come by and see the person and the bed/ chair they have been in they will then be able to teach you how to manage a bed sore.
if your not able or willing to follow this minimum 2 hour change in position then ask for help from the doctor he may send community nurses to help part to the day or he may have the person admitted to a care home for there own good .
