Hi, I am a 28 year old female. I have two questions, I have a bump underneath my right breast and is currently swollen and sore the other is that just randomly my right sight of my head and neck get the feeling as if it is losing circulation, the getting numb kinda tingly feeling. The swelling and soreness just started recently and the random numbness has been going on and off for a couple of months and a couple years ago I had the numbness and it has caused light blackouts in my vision and I get really light headed/dizzy, that still happens though every now and then.
