Welcome to HealthcareMagic forum,
mohit what you have is called HYPERHYDROSIS .There are two ways you can deal with this.One is a simple solution available in market i.e. formalin solution which can be applied over the affected area.Some doctors have a machine called IONTOPHORESIS
which can help you in this.In medical shops you get a preparation called NOSWEAT spray..which again can be tried.And if you are looking for a costlier treatment then you have BOTOX
injection which works wonders, but is temporary .So consult a good dermatologist
who can suggest you the above options.
