I suffer from cmt type 1a. For about 8 years now my right knee has been causing a lot of pain and it (in the only way I can explain) gets stuck in a bent position and then has to be pulled and cracked back into place before I can walk on it again. It hurts but I'm so used to it now I can handle it. However recently when I've woken up or sat down for a while a bone right on my inner pelvis feels like it dislocates, I can't stand and the pain brings me to tears. The other day I was forced to slide around on the floor in agony while dealing with my two young children until it cracked back into place (which was also excruciating). Has anyone else had any experience of these sorts of pains and any advice on how to deal with them? I can't take any medication aside from co-codamol as I am breastfeeding.
