<s>[INST] I woke up this morning with pain when I lowered my arms, under arm pits.  When I looked in the mirror i had a lump dead center of each about twice the size of a pea.  I also have a rash on the skin in front of my arm pit to the r/l of each bra strap.   I have been taking a lot of motrin , alieve and advil for knee pain. I have stopped all today.  I am healthy eat well and work out alot. Help [/INST] Hello! Thank you for the query. This lumps in both armpits can be enlarged lymph nodes. Enlarged lymph nodes can be caused by an inflammation or some cancer (including lymphoma). If you have also fever, weakness, night sweats, weight loss, cancer is more possible. I suggest you to do not ignore your symptoms. Please consult your doctor. Blood work and armpits ultrasound should be done. Hope this will help. Regards. </s>
