I had a knee replacement 2 years ago (am relatively young for one but have had wonky kneecaps since birth so my knees have worn out faster than they should) in one knee. Recovery has been very good. Am at the point now where everything had settled and was doing well. However, every so often I get this incredible stiffness that comes on suddenly around the knee area then intense pain, exacerbated by painful spasms at the back of my knee and upper calf - the pain radiates down and up my leg. I can hardly walk and my knee becomes unstable (the intense spasms make it buckle underneath me).
At first I thought it was directly down to the replacement itself and saw a consultant re my knee in December but its fine in itself.
I now feel its because of the op the FM has apparently begun to affect this area more (at the moment anyway).
Found an interesting article re this and it does make sense
And bizarre as it may seem had a chat with the vet/physio that treat my dog (they're probably more qualified than my GP is and any physio they might send me to) and she put me on to back on track products as I need support for me knee when I walk the dogs (something that gets me out) and have now ordered a knee support, which look very interesting particularly in the cold weather we have now
Am trying to work my way through this as its so painful and debilitating when it occurs - the pain is as bad as it was when I first came out of hospital after my knee op but am reluctant to ask for morphine when it happens (am currently on tramadol, gabapentin and paracetamol) but it means I can't work because of the pain then and can hardly walk but then am not eligible for any benefits either as it while in pain I can carry out most tasks but may not every day
