Hi ramesh apply bakson's aloevera calendula cream daily 2 times a day on your affected part.
Homoeopathic medicine named apis mel 30 & arsenic 30, take 4-4 pills of both medicines together at 1 time, like this 4 times a day you have to take it. Do not touch the medicine. You will get it in homoeopathic pharmacy only.
Do this for 1 month & reply back after it. Stop all other medicines cetrizine
& levocetrizine no need to take that. Thanks.
