for about a week i've had pain in my left armpit. i thought i just cut myself shaving but yesterday i felt a small lump under the skin. it's not red or visible really, it's totally under the skin. i am considerably freaked out because lymph nodes are located there and i'm terrified its lymphoma, cancer. i am going to the doctor on tuesday to have it looked at but in the meantime can anyone comfort me and tell me there are a million reasons for swollen lymph nodes other than cancer? has this happened to anyone else?
