Hello. Swollen lymph nodes prompted me to take a look at my throat a few weeks ago. I found several small white-ish lumps on the back of my throat. I don't have medical insurance currently, so I started taking the rest of my girlfriends antibiotics that she had leftover (erythromycin base 333mg ec tablets). I took 4 of those pills over the next few days and the swelling was gone, however the lumps on my throat remained, to this day. I have no cough, fever, shortness of breath, pain, or any sign of sickness that I am aware of, just lumps on my throat. What could these be? I don't know if this is related but I have also been having small discomforts with gas and heartburn-like feelings in my chest (maybe acid indigestion?) beginning before I noticed the lumps in my throat. Thanks in advance.
