Nasal infection symptoms and conditions

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.

Was prescribed Doxycycline for nasal infection. Wound up being hospitalized twice for extreme lower back and abdominal cramping. More intense pain than I have ever felt. My skin was covered in rash and itching, presumably due to the antibiotic as well. I found that consumption of milk products highly agitated these symptoms.
