I have peripheral neuropathy in my hands, feet, and tongue, which has been diagnosed but with no known cause. I'm 39 years old and have had it for about 4 years. The symptoms include slight pain and discomfort, and they seem to worsen with adrenaline release, stress, alcohol, and caffeine. I also have herpes, which exacerbates the condition during flare-ups. I limit my alcohol intake to 15 units a week but occasionally drink more. I've had B12 injections and various tests, including MRI, brain and upper spine scans, blood tests, and nerve conduction tests, all of which came back normal or showed mild to minor neuropathy. What could be causing this and will it continue to progress?

I am not in shape and have high heart rates sometimes when walking around the house. I've had two normal EKGs but still feel scared to exercise. Is this due to being deconditioned, and should I start exercising more?

I have a painful, non-itchy rash under my left armpit. I recently switched deodorants and noticed the rash tonight. I am 24 years old, male, and take Welbutrin and Viibryd daily. I had unprotected sex in early June and had an HIV test a month later, which was non-reactive. Should I be concerned about the rash and the HIV test results?

Dr. David, I know you say AI's work better than tamoxifen. I think you've said 60% vs. 50%. Can you show me an article that says that and clarify what the 60% refers to in terms of AI therapy?

I experience numbness in my right leg with pins and needles starting in my buttock, causing a weak feeling but no actual pain. Sitting down briefly alleviates the feeling. I now rely on a rolling walker for confidence to go out. Can this be cured?
