Dh had an op on his leg in March - he has bad arthritis, needs a new knee but instead of this they broke the leg, inserted pins and cut a section of bone out. Apparently this is cheaper than a knee joint. But that's another story.
Anyway since he's had it done he gets a violent tic in it during the night. It wakes both of us up several times. The only way I can describe it is shakes and vibrates and bangs the bed. DH says it's like it's posessed, not cramp something entirely different.
Anyone have any experience of this? Surely it's not normal. The whole op has been rather a cock up.
