Zithromax Z-Pak and skin sensitivity

I had severe flu like symptoms (fever, body aches, bronchial congestion). My doctor prescribed zythromycin as a precaution since my son currently had pneumonia. Within a day of starting the 5 day dosage, I started having severe skin sensitivity. No other way to describe it but a bad sunburn over my body. It hurt just to have clothes touch my skin. Not sure if it was from the Zpak (my doctor didn't think so) but it sure seemed coincidental if not. Pain lastest for days even after going off meds.

I've taken Zpak several times (4+) and each time, it worked like a charm to cure ear, nose & throat infections. I think it worked better for me overall because of the short-dosage cycle which made it easier for me to take the full course prescribed (2 first day, 1 every day thereafter for 4 days). Side effects: diarrhea, cramping, headache, feeling "high" or medicine head--taken with or without food. Hard to say if these effects are attributed to meds or to the infection itself. Boyfriend taking Z-pak right now--he reports severe body ache, skin sensitivity (to touch), and feeling like crap. Again--hard to say if from med or virus/bacteria.
