Sounds like a circulation issue, since one of the effects of meth (and other stimulants) is to constrict the blood vessels. But I'm no expert - it's probably worth checking with an open minded doctor, if you can find one.
Yeah - not me personally - but back when I was using meth a lot and was hanging out with others doing the same, I knew a few people who'd swell right up. I agree that it's probably a blood-circulation issue.
Now I don't have swollen calves. My toes feel numb. I do have fibromyalgia and that can be one cause. It's interesting as it's mostly my right foot and it's isolated around my toes and the top of the area beneath the toes. Weird. I don't smoke every day. And I don't stay on my feet alot but I do excercise them. It's weird. I do take Lyrica for the fibromyalgia. It sorta helps. Any one else experience this and if so have you found a relief?
