Bumps on the head that come and go.

[Pray]

Hi,

I am 1 year out from chemo, and 6 months out from a year of hecepten. In the last 24 hrs. I have had 3 different lumps come and go on my head. One on the forhead, 1 on left back side of my head and one above my right temple(which is still there) has anyone ever had these? The lumps are the size of half a grape.

Thank you for any advice or comments.
