Hi, I am a 32 year old women and within the past few weeks (maybe 2/3 weeks) I am experiencing numbness and coldness in my lower left leg around the front of the leg. At night I have started get leg cramps which I never have had before. I do smoke also. I do eat healthy most of the time and exercise 3/4 times a week but I haven t done any exercise within the last month. Could this be a reason for this sudden numbness? I am really starting to get worried about this. Please help.
