I can feel this small ball under my arm(bicep). It's sore and feels like it's in the tissue of my arm.?

Question

I've also had one in the back of my leg before that used to hurt and doesn't now but I can still feel it. What are these?

Answer 1

It sounds like you have swollen lymph nodes. They are glands located in various parts of the body, including under your arm, to help ward off infection. If they become enlarged and become firm, as yours has, you might have some sort of infection. In the meantime apply warm wet washcloth to the lump for 20 - 30 minutes 3-4 times a day if it is painful or tender. The heat and moisture can speed up healing. It may or may not be serious, but I agree that you should see a doctor.

Answer 2

My sister had something similar and it turned out to be a cyst please see your doctor to get antibiotics

Answer 3

If it is hard and it grows, it may be a tumor. It could be anything, including just a simple skin irritation. Try using witch hazel to soothe the skin. If it doesn't go away, see a doctor.

Answer 4

go to the doctors now.  

Answer 5

i think ive also got that if you contract your bicep muscle you can see it. i get it more after i have worked out i thinks its normal........... hopefully it also feels like its on a artery or big vein dont worry just think there is someone out there with the same thing. but if you are still worrying then i would go see a doctor. =)

Answer 6

its probably just a cyst but you never know, cyst's are harmless and are just like buildups of fat and other stuff, but it could be something else so you should probably go to a doctor.
