I had a lateral release and also some arthritis tidied up, one week ago. Like you all, there is a lot of swelling and huge amount of bruising. Every day I wake up the bruising has crept further up and down my leg! It is now right up the back off my thigh (dark purple) and even on my foot and round ankle. It's such a relief hearing others say they've been told it's normal as I was starting to worry, so thanks!
