The strange thing is that after my acl and medial cartilage surgery, I did have intense 'hot coin' feeling on the inside of my knee where I have 1 stitch and almost cried when they removed it with. All the other 13 around the knee where totally fine with only a little pinch.

However as time passed my operation healed fine and was back to full activity, running, bike, gym etc without any pain whatsoever until 20 months after the op. Wouldn't go skiing but you get the point. It did heal slightly tight but never bothered me to be honest.

The pain started 13 months ago after I over strained the knee and spent 2 months not letting it settle down by continuing normal daily activity however did not have constant pain, only pain from walking, fishing, driving too much or when keeping the leg straight too long. This was until a physio pulled my leg out several times which is what we believe caused my rsd as my pain then became constant and difficult to control but the funny thing was than when I kept it bent I had no pain at all. This is what mixes me up the most and still does! I was able to turn the pain on and off at the time and although the pain is way different now, the pain only allows for me to be seated with my thigh parallel to the floor and cant be in any other position or angle, otherwise I would get intenser pain.

I know crps is a monster but it would at least clear my mind to know what exactly was the initial cause of it and if it has to do with that spot from surgery and if so is it possible to fix or treat as opposed to the crps
