burning what could it be ?

Photosensitivity?: Sulfamethoxazole-trimethoprim (Bactrim) can cause photosensitiivty, which may last longer than an allergic rash. Basically photosensitivity is increased susceptibility to sunburn, so this is especially likely if the burning sensation is mostly on sun-exposed areas and if there is actually redness in those areas; most common in sunny areas like Arizona. Contact the doc who prescribed the Bactrim.

Accepted Answer

Allergic reaction: STOP!!! And do not ever take a sulphonamide again. This class of antibiotics has a very high frequency of allergic reactions and some of these can be life-threatening. If this doesn't get better quickly or god forbid is getting worse go to an ER and get seen. Best wishes.
