Weak leg after spraining ankle

Haven't heard anything like this before, but I guess the problem with your hamstring can be diagnosed by physiotherapy. I had a similar problem with my hamstring for a long time and I was finding it very difficult to stretch my legs. I was not able to run for more than 2 or 3 miles. I tried many stretching exercise at home and nothing worked for me. Then I consulted a physio in Toronto of the Physiomed clinic ( http://www.physiomed.ca/) and I had 2 months of physiotherapy with him, which relieved the hamstring pain to a great extent. So it would be better to get an advice from a good physiotherapist regarding your problem.

If I could motivate myself for another doctor's appointment I guess I would, but to me this isn't that critical at this stage. I should have scheduled an appointment when I couldn't be seen at the ER, but after waiting 13 hours I was over it. I bought myself a crutch, iced it, and waited it out. If it starts cramping more I will definitely schedule something.

It's an odd sensation. My 13 mile bike ride yesterday, 2 miles into it, my calf was screaming with lactic acid and started twitching, then the fatigue and burning creeped up behind my knee, then into my hamstring. I ignored it and just kept pushing through and it's like I got a second wind and all the burning disappeared by mile 6. It does that kind of thing while running too. It starts in the calf and works its way up. I can ignore the weak feeling as long as I don't start cramping. So usually it's just a comfort thing and doesn't affect everyday life so I don't complain much.

I have come a long way. Like you, there was a point where I couldn't run more than a couple miles, but gradually built my mileage back up albeit with some pain, but 2 years into training I improved to my current condition then just quit improving.

I asked someone in the medical industry a while back, and they think the sprain was severe enough that my tendons and ligaments didn't heal completely, and damaged some nerves increasing atrophy from my initial disuse.

I have seen veterans with missing limbs, and people with muscular and neurological disorders finish these things so I know my condition is nothing by comparison, I'm just curious how to minimize discomfort and cramping.
