My mother is 60 and is a diabetic. (type 2), she had varicose veins and had an operation for it 10 years back. For the past 1 month, she has been applying dynapar qps daily on her legs, 5 to 8 pumps, but for past 3 days she says that her legs are burning and it stings, she feels like air is passing through her toes. Is it caused by the medicine? What should we do now?
