Hello Doctor, I am a 66 year old male - height 5.8 weight 190 lbs Asian and I am Diabetic, but under control with medications. For the past several months, the blood circulation in my feet and hands is poor I think, due to which I get numbness & tingling sensation. I was in India on a vacation in 2015 and a Doctor prescribed me Nerv UP OD which I am taking one a day regularly. It has helped to some extent, but not very well as I expected. I think the condition I have is called Peripheral Neuropathy. Could you please advise me something better or give me a referral to a Doctor in zip code 60101 area. Thank you.
