Reaction of Ayurvedic med or chicken pox

I was taking ayurvedic medi for pcod and piles since 1 week. Suddenly i developed fever and next day there was rashes on my whole body including face, neck, back and thighs. I developed fever 102-104 and the temperature become normal after 24 hours. The rashes started disappearing after 2 days and now there is just blackish sort of marks on few areas. But i still feeling itching sensations. May i know whether it was chicken pox or due to heat of Ayurvedic medicine I developed some allergy. The same doctor wrote anti allergic medicine through video consultation but he wasn't able to tell the exact reason so i didnt took any medicine. May i know some home remedies as with such weak immune i cant take the risk of visting doctor.
