Hi thanks for asking question. Here according to history it is most likely to be viral infection. It may be chicken pox if you have not in your childhood. It is better for you to take enough rest. The treatment is mostly symptomatic. Here is some suggestion for you. Wash hand frequently. Avoid to go in crowded place. Tulsi leaves, rice starch,dry ginger mixure is helpful. Drink hot water and soup. Take semisolid diet and eat more fruits. If your condition still not improving then consult doctor. Simple analgesic and antiinflammatory drug will be helpful to you. Thanks.
