I Dont know if this is all.connected or not but im a female...my lymph nodes keep swelling up..one was really painful under my arm and another small one appeared just underneath my.collar bone...I have a itchy.rash between my breast and sometimes I feel a light pain in my arms and legs..like shooting pain.....sometimes I feel like im walking around in a daze......and sometimes I feel a weird pressure in my head by my temples but it doesn't hurt....I've noticed some changes in my vaginal discharge it's white and thick after my period has been off for 2 weeks...and today while I was smoking a black and mild I could hear a pulse beating in my ear..what do u think is causing it?
