There is a knot under my arm making rest of arm feel numb?

Q: A couple of days ago i got something that i believed to be an ingrown hair in my under arm, so i didn’t mess with it. A couple days later it had got larger and became painful (also little ones began to come up around it). This morning i woke up and it felt like my entire arm had no blood circulating, as if it has been raised above my head for a long period of time. Could this possibly be somthing other than an ingrown hair and should i go see a doctor?

A: I would say it’s a cyst, which would mean don’t stress it, but with the numbness you should give it two or three days and if it reoccurs see a doctor.

Small knot under arm, worried about it being cancer?

Q: I am 18, and this morning i found a small knot under my arm. It is a bit tender, but not really and unless i touch it i cant tell it is there. I go to the doctor monday, but i am really worried about this. Any ideas? Am i right to be freaking out, or am i over reacting?what kind of infection could it be?

A: Yes there are many lymph nodes in the armpit, however they are somewhat deep in and you would most likely have more then one lump. From what you posted, it sounds almost the a deep boil. You can get ingrown hair, or sweat glands and it can cause you to have large cysts. However, with that, I suggest that you get seen by your Doctor ASAP. Without scaring you at all, a lump between my mom’s armpit and breast was how they found her breast cancer. As for the kind of infection, you can have a staph infection if it is a boil. So that is another reason to go get seen as soon as possible. Good luck and don’t worry about it until you see your doctor. Also, try not to touch it much, you could irritate it more without meaning to. HUGS and good luck.
