Hello friend, I am a Homoeopath answering your question through Health care magic. Soaps including bar soaps are a common material we use in our daily life. When it started to be your enemy is not mentioned in your question. Surely there will be a point of time when it all started. Now your duty is to find out from which anecdote this allergic reaction started. Then you will also find that it was after a particular conflicting incident in your life that this allergic changes started. This must be related to some unexpected shock, a separation, death of some loved ones etc. prior to the onset . All allergies have usually similar connections with the mind also. Unless this is brought to light, your exact mental make up cannot be understood. In Homoeopathy, we take into consideration your the mental, physical and general symptoms to find out your constitutional remedy. My advise is to approach an expert Homoeopath at the earliest. In Homoeopathy, we need not even avoid the material which causes allergy. While continuing contact with bar soap itself, the sensitivity is corrected. With best wishes for curing your problem through Homoeopathy, Dr. C. J. Varghese Homoeopath drcjvarghese@gmail.com
