DEAR DR. GOTT: About one year ago, I read your article about soap under your bottom sheet. To be sure, I put two bars under my sheet. I had complete success and have never had any cramps since then. Now, my legs have turned black - I mean ugly black. The doctor said it's poor circulation. Could the soap have any effect on this condition? I should add that I am very old. I would appreciate some reassurance.

DEAR READER: Nocturnal leg cramps may reflect poor vascular circulation to the lower extremities, as does darkening of the skin. You should probably consider an ultrasound exam of your aorta and leg arteries to check for blockages. It may be that poor circulation, if present, can be treated with medication and/or surgery. Check with your doctor for a thorough evaluation and further advice. If he is unable to help you, request a referral to a vascular specialist.

DEAR DR. GOTT: I have chronic constipation. Nothing helps, and it's gotten worse since I had a hysterectomy back in 2004.

If you have any advice, I would so appreciate it.

DEAR READER: I wish I had a magical cure for chronic constipation, but I don't.

Many patients have experienced relief from this common problem by drinking 8 ounces of hot prune juice in the morning.

Others have chosen a “colon cocktail” (1/3 cup bran, 1/3 cup prune juice and 1/3 cup applesauce).

If ineffective, this solution can be followed by prescription drugs, such as Peri-Colace, to soften the stool and assist in its evacuation.

If the problem continues, I recommend a referral to a gastroenterologist for further testing and advice.

Ask your primary care physician to become involved, if necessary, in addressing your problem.

To give you related information, I am sending you a copy of my Health Report “Constipation and Diarrhea.”

Other readers who would like a copy should send a long, self-addressed, stamped envelope and $2 to Newsletter, PO Box 167, Wickliffe, OH 44092. Be sure to mention the title.
