My throat (internally only) has been irritated, hurts, and makes swallowing even saliva difficult. Separately, (but related?) I have had a reoccurring rash, of small red spots on my body, mostly abdomen, but arms and upper leg occasionally. These come and go, but have been noticeable for several months. I am a gay male, and wondering if this could be a possible STD, and whether the symptoms are related?
