About 5 months ago I found a lump in my right breast. I seen my PCP she had made me a mammogram and ultrasound appointment. Mammogram came back okay but ultrasound showed something that they said looked like a cyst but she said she wasn't sure to come back in 6 months. Around January I started having pain in my right breast and underarm it has started to get worse by the months. I now am having numbing in my hand and filling very fatigued. I woke one day with bad pain in coller bone and neck it was from my breast and arm to the neck. I went to see my PCP she told me I was having this kind of pain because I pinched a nerve and breast pain was from was from my period but I had my period 2week ago. I had told her why is my underarm swollen she said quite playing with it. I don't know what to do I am in pain and feeling horrible. I can't understand what this could be if my doctor is telling me I have nothing wrong with me.
