My mom (39 yrs) is having itching problem since 1999. But now a days this problem is increasing very much. She can't able to sleep properly due to that. Palm n feet palm full itches at night. We also showed Dr. but medicine are not working. Please say some medicine so that her problem gets solved. Currently she is taking HHelevo medicine, this is good. But please do something tell. I heard zinc ointment is best for skin related problems. please suggest as early as possible, I can't able to see her in problem.
