My hubby has problem of itching (kharish) from past 5 years on regular basis. This itching spreads all over body in a vigorous way with big patches which is incurable. Consulted many doctors, one concluded they are allergic to sweets, and advice to take medicines, but this itching is non stoppable, I want to know the exact reason of this, and want to finish that. Medicines they took in past 3 years are LCZ, Atarax, qubast- 20, and presently Wave- M. Please guide.
