Hives Treatment

I contracted severe hives on my palms after applying a deet based mosquito repellent on mosquito bites. I have already stopped using the repellents, but the hives persist. I have tried many things but to no avail. I have finally found some relief by soaking my hands in a solution of diluted hydrochloric acid. The itching sensation has gone, but I am not sure if the hives will come back later. I will post back.
