I've been trying to start running, but after a couple 20 minute sessions I started getting really bad pain in my calves and occasional muscle spasms. I can still walk for a few miles at a time without it getting too unbearable, but it's quite painful for me to run now. This is not
normal soreness, but I have no idea what it is.
Does anyone know what this could mean? I seem to be prone to minor running injuries. When I was thinner I ran more and ended up with (what I thought was) a stress fracture, but I had to take painkillers constantly for assorted knee and ankle pains.
