Botulinum toxin (Botox) is usually quite safe in expert hands. A last resort is surgery to remove the sympathetic nerves to the scalp, a procedure that’s very effective.
DEAR DR. ROACH: Some time ago, I had a lot of noise coming from my stomach, a kind of growling sound. It stopped for some time, but now it comes on again once in a while. No pain, just the noise. -- T.
ANSWER: These noises go by the official-sounding name of borborygmi (BOR-boh-RIG-mee), and are both common and normal the vast majority of the time. They reflect the movement of the stomach and the intestines. Since there is no pain, you don’t have to do anything about them.
DEAR DR. ROACH: I have heard that magnesium destroys vitamin B, and vitamin B keeps you warm. I am cold all the time. I take magnesium for a delayed heartbeat. Do you think that magnesium is my problem? - H.A.
ANSWER: I also have heard that vitamin deficiencies, including B vitamins and vitamin D, can lead to intolerance of cold. However, I couldn’t find much good scientific evidence to support that, and none at all that magnesium causes problems with vitamin absorption or activity.
Low thyroid, hypothyroidism, is the first condition to come to mind with cold intolerance, and anemia is the second. Although it can’t hurt to try a B-vitamin supplement, I would recommend getting checked out for these conditions.
