I have this horrible pain in my left calf that feels like a sharp stabbing/cramping/vise grip-like torture and there doesn't seem to be a pattern for its occurrence. Sometimes it comes when I'm standing pretty still in one place (cooking, washing dishes), other times when I'm walking, and still other times when I'm sitting. I get temporary relief from stretching that leg, but maybe for just 2 or 3 minutes, then it comes back. The thing that I can't figure out is that I now have a skin indentation on the very spot that hurts, and it seems to be slowly getting more noticeably indented. I just recently discovered that if I push into my calf hard enough right into the area just next to the indentation, I also get temporary pain relief. The other strange thing is that it's not constant but it can take definitely happen for the majority of the day with a little break here and there. I also have spondylolisthesis of the L5-S1 region with a probable nerve impingement there that causes leg pain and numbness on the same side as the calf pain. AND I also have a flat foot on the same side which is severely pronated. I've had this leg/calf pain for the last 2 - 3 years and always thought it was because of the nerve impingement. Now, I'm wondering if the calf pain is due to something else because my Dr. prescribed me Lyrica (for nerve pain) and all the other leg pain and numbness was substantially decreased and/or gone -- except for the calf pain which stayed exactly the same. Does anyone have any ideas what this calf pain/indentation could be? I'm 37 years old and weigh about 125 so I don't think age and weight have anything to do with it :). Thanks!
