Ok, so I have a stinging and itching pain on my back, not my legs. And this happens to me when it's VERY hot, or stressed out. I get it lots of times everyday! Many people says it's because of your nerves. But I never heard of stinging pain when it's cold. Maybe it's the nerves just like my problem! Hope this helps.
Hello.
Can you mention how long have you been having this pain ? And when you leg, do you mean the area between the knee and the ankle (medical definition).
There could be a number of causes like neuropathic pain or problems with blood supply in the cold weather. Do you get discoloration of the toes ?
Regards
