Caller states when she got the vaccine on the 27th, the thing that she put on her arm after she cleaned it with alcohol that is a newer type of bandage had like a film ring and a film on top of it. Caller states she then put a Band-Aid on her arm and it bled threw that bandage so when she got home she put another one on and left it for about 26 hours for the bleeding to stop. Caller states the lump on her collar bone is about an inch and a half in diameter maybe, therefore the size of a larger grape directly to top of the bone. Caller states it hurts when she puts any type of pressure on it and it hurts considerably more than the aching that is there. She would say that in diameter the lump is maybe an inch or an inch and a half. She can still feel that it was there today and it might have grown a little bit. She can't tell if there is fluid around it. It could be that she is more alert to it and a little bit paranoid. Her skin around the lump is puffy but the lump itself she can still feel. When she gently presses on her skin it feels like there is fluid around it. Caller states she does not have any swelling of the lymph nodes in her armpits or under arm but possibly a little bit of swelling in the lymph node under her jaw line but does not feel the bulge that she feels on her collar bone. Caller stated in 2 hours it would be 48 hours since she got the 2nd dose and the thing on her collar bone was very prominently still there but it was not there prior to receiving the vaccine. Caller would like to know if this is not something that is happening, should she follow-up with her PCP and get screened for any lumps and bump that may be associated with breast cancer? She had already talked to her pharmacist who had warned her that lymphedema is something that you might can get, but the lymph nodes in her arm pit are not different. Her only question would be, is this a side effect that has been reported before or if this something more serious that she should see her primary care provider for?  No follow-up attempts are possible. No further information is expected.
