I'm in my late 40's, slim and pretty fit. From time to time I suffer from inner knee pain which can affect either knee in an identical position. I tend to think it might be a pinched nerve because it's very painful and tends to go quite quickly, though if that were the case I would think it odd to be a pinched nerve (does that make sense?)
I have added a picture, the pain is very localised, I think I can pin it down to an area no bigger than a 50pence piece.
It can come and go at any time, but is more likely to show its ugly face on a longer run. I am currently only light jogging 1.2 miles on a grass sports field in the morning and 1.6 miles on the same field in the evening. So less than 4 miles a day and on a good soft surface. At the moment I am ok but I would love to hear the opinion of an expert and perhaps find an exercise to help correct this issue that has been troubling me for several years.
Many thanks in advance.
