i have a problem of having allergy only on the skin part that comes in contact with plants like grass, trees, straws, etc. The problem gets cure itself after some hours. Not by simple touch this problem arises, but when the skin gets fine scratch for sometime by these plants. Also, not everyone have this kind of problem.
why this problem occurs to some people (like me)? what is limiting in my immune system so that my body cannot defend against those bacteria? how can i boost my immune system particularly to prevent such infections?
