Discomfort in the Left Arm and Armpit

I have been feeling a discomfort on my Left arm and armpit for about a month now..a feeling of tightness and tiredness and sometimes pain on my left arm, underarm and breast area..I went to the doctor and she checked if my underarm lymph nodes are swelling but she said it's not...so she had me mammogramed but it came out normal..now I still feel it...and been having night sweats for a few days now...not a severe sweating but enough to wake me up and feel sticky in my neck area....is there a reason I should be worried???I'm 30 years old and my older sister was diagnosed with non-hodgkin's lymphoma for a few year now...

Hi adin22,
Did your doctor mention anything about hormones playing a part?  I've had pain in my breasts and armpits, off and on, and usually I notice it in the mornings when I get up.  I do have NHL, and I developed this pain after treatment.  I spoke with my doctor about it and they checked my lymph nodes under my arms and sent me for a mammogram, but they didn't find anything significant.  I was told it was probably hormones since chemotherapy can really mess with hormones.

Hello, Thanks for the reply...my PCP didn't mention anything about hormones at all....but I think my obgyn checked some of my hormones 3 months ago and everything was fine....but I will ask  them about it...Thanks....
