I have a swollen lymph node under mmy arm , I am a daily meth user( (syringe ) the area is the size of a pecan , and this morning it began to seep . I drained as much as possible but I am feeling a little dizzy and I can tell me body is drained and I feel like I am stopped up in my ears now like a head cold I am lethargic and deeply concerned , I have penicillin from a friend but want to know if I should take them in regimin or go to doctor or emergency room .
