My hand is all red with scars. It has been happening for 5+ years in mostly when temprature tends to rise. Its gets bad when curring fruits & vegetables pecially those which excrates juies (onion, ginger, tomato, papaya etc.) all medication be it alopathy, ayurvedic or homeopathic has not been of much help much till now. It gets so bad at times as I am unable to fold my fingers & in case finger folded with much effort, skin ruptures & blood comes out. Please suggest what should I do to improve & ultimately get rid of this problem
