I went to dominican republic recently and have developed a red bumpy rash what could i use for it?

Cause must Diagnose: I am sorry to report but before a treatment can be recommended that cause of the problem must be identified. Please go see you family doctor or a good skin specialist.

Can't make a : recommendation without knowing what it is. This rash needs to be visualized & a history needs to be obtained in order to make an accurate diagnosis.
