hi doctor, i have a lump under my arm and i have had it since 2011 when i first noticed it i felt pain but then it went away after about 2 weeks. I went to the doctor because it was still there but the pain went away and she told me to just put a warm rag up under it and it should go down. I did just that but it never went down. Then last year my lymph node under my neck was swollen real bad and was sticking out so i had to go to the doctor to get antibiotics to help. i ave swollen feet and ankles every now and then if i take in too much sodium. I am anemia. So just recently i had my period with really strong and bad cramps following with a headache for the last three days. I noticed a smell fro my armpit but didn t know why it was there so i washed and put deodorant on and it seemed to work for awhile. Then three days later the lump under my arm started hurting again and i noticed the foul smell again and i thought it was from me sweating and it just made a smell. so today i decided to wipe the sweat off from my under arms and while i was wiping i noticed puss coming out and it had a really bad foul smell. Please help me with what i should do. Thank You.
