What can I do to relieve bedsore pain?
You should think about taking nonsteroidal anti-inflammatory medication since you need to relieve pain from your bedsores. Topical pain medicine has also been known to help if applied while the new dressing is being put on the area.
Don't lay in bed so much, roll more often if you have to stay in bed. I don't know your circumstances as to why you get bedsores so I won't guess.
