hello, im 18, i have been having some concerning symptoms that come and go. this is currently the 3rd time theve occurred and are sticking around longer this time. in my left breast my nipple is so irretated and kind of hurts. when i press the bottom of my breast it hurts alot and at the side of my breast kind of on my rib cage. when i press it, it sends an almost shooting pain through my whole breast. this is a new symtom i think. it usually starts about ten days before my period and is completly fine bt the time my period is ginished but my period is practically ended and although ig has gotten slightly better its still here. I have a sort of anxious tick i guess you could call it. where i sort of vigoresly shake my left hand and whole arm kind of. could it be a muscle ive pulled due to this? i found a lump in my right breast and went to my gp who has referred me to the breast clinic but the appointment isnt for another month. im hoping you will maybe have some answers to ease my anxiety on this until the appointment. and if it is something more serious like cancer, will the fact that its taken a month to get it checked make it harder to treat?? thank you so much
