Hi I am a male 21 years old and I have a lump under my right armpit and on my inner right arm right above my elbow. Its been going on for about a week and some days its just those two spots and other days its sore and painful from the armpit to midarm/elbow. This pain is mostly a discomfort until I raise my arm up then it hurts pretty bad. If I take the hottest showers ever it feel a little better for a little while not too long but it helps somewhat. A few days after I notice it I thought it was going away but then some one pull on my arm and a few hours later it was back to hurting/bad discomfort. I don't know it that's why it went back to hurting because of the pull or just because it was going to no matter what. If ANYONE could help me out and tell me what they think it may be it would be great. To let me know how long I should wait to see if it goes away before I REALLY should worry. OH ONE MORE THING: PLEASE do not tell me to go to the doctors to get it looked at, I would have done that before writing this but I do not have insurance and cannot afford it at the moment. So any help would be GREATLY appreciated. Thank you.
