I've been getting pain in both knees in the area between the bone and outside of skin on the insides of my knees. It's just that area of tissue. I did a really big walk about 2 months ago after a hospital appointment - I walked home through the park. I couldn't resist doing this same walk that I used to do when I had once worked there. I knew I shouldn't have but it was so tempting and a lovely day. Ever since I am quite sore and feel streaks of pain. Kind of feels like something is taut. I also feel like I have put on a bit of fat on the insides of my knees which is a surprise considering it's been hard putting on weight during this whole illness. I'm now wondering if there is slight swelling perhaps. I thought it would have gone away by now but it feels just the same as when it first began a few months ago. Anyone else get this and any ideas what it might be.
