While i am sleeping,i wake up to severe pain in my knee while shifiting my sleeping position.It feels hot and if someone is trying to pull it right off to the point of screeming.I can't move or bend.This lasts for around 30 seconds.I have had this problem for the past few years.I don't understand what is wrong.I looked and my left knee does not look at all like my right knee.It is dented but does not hurt when i touch it..This only happens at night while i am asleep.What do i do,what is going on?
My best suggestion is you make an appointment with your doctor as soon as possible to get checked out. None of us would answer questions here are doctors and some questions really need that specialized knowledge and I think yours is one of them. While you wait for your appointment, you may try to put a pillow under your knee or between your knees, if you sleep on your side to make your sleeping position more comfortable. You may also try to take a painkiller before you go to bed.
