Zithromax Z-Pak and rash

I get some stomach cramping from the Z-Pak, but the most disturbing side effect would be the chest pain. I have swollen glands right now and I had vertigo and the doctor told me it was probably a bacterial infection because the gland under my chin is the one that is swollen. Every time I take this medication the side effects are different. I also had the agitation the last time I took Z-Pak. Sometimes I have had the lose bowels, especially after taking the two pills together the first day. Well, I guess it is better than having an infection so I will continue to take it. There are other medications that are worse for me. At least I am not getting a rash and I cannot take penicillin.

I'm a 32 year old male. This is probably the 5th time I've taken Zithromax. Unlike previous experiences, this time I got a horrible rash on my face, chest, neck, and little red spots all over my body. They itch horribly and I'm hoping they go away on their own. I am going on week two and they are still around. Last year, I was given a very strong antibiotic for an infection that just wouldn't go away. I took one dose and threw the rest out because the resulting full-body rash was horrible. I think that some of us may develop an allergy to certain families of antibiotics as we age. Either that or our immune systems are degraded. Who knows. I've also been dealing with chronic anal itch for 2 years now, and that is a horrible thing to live with. FEELING OLD!

I developed a painfull rash around the anus. Has anyone ever gotten that?

Third app't at dentist . Premed with 500 mg zithromax; also took it two other times within month. I took 500 mg one hr prior to app't .

Did not report as I was eager to get tooth extracted and had improved quickly , had never exprienced the weight feeling in chest before.
Noticed in past month forehead itching and eyelids a bit swollen and itchy on lids also felt spotty raw areas sore. Face felt hot over past month
I have had problem with palpitations and breathlessness with Doryx and Cephadroxyl until I had finished both series. It left me entirely as I stopped except for a couple events slight a couple times for a couple months after. Ihad thought the infection had affected my heart it was over my sternal region . the infected cyst did not improve however with z pac cipro and the doryx and Cephadroxil until entire cyst was removed.
Penicillin drops in my eyes left half my eye flame red . had a local reaction to penicillin injection in oil 1948. Rashes from
