Some days ago i had very bad itches and when i used to scratch it , my skin would appear with bumps irregularly shaped and along with that my palm would swell and feel itchy and my palm would go red .It was normal after sometime and at that time i was under medication for fungal infection. My doctor has given me 1 al tablet for the itch . I wanted to know what causes my palm to swell and why does it itch ? Is there something i should avoid in my diet because this problem has started recently i never had this in the past. Please tell me the cause .
