I found two bumps at the base or near the hairline on the left posterior side of my head approximately ten years ago. A general surgeon said they were nothing to worry about unless they changed in size. Recently, I found a third bump more on the right posterior side of my head approximately two inches higher than the other two bumps which still remain. While they could be small cysts, as I had one on my forearm removed and have one on the inside of my left knee, I am wondering if I should have these "bumps" checked. The bumps are all approximately the size of a dime. While I have not noticed any neurological symptoms relevant to language, memory, etc., I occasionally have tingling, numbness, or a hot feeling on the right side of my face, as well as occasionally getting headaches that are more focal in nature either in the left temporal or the posterior part of my head. I also recognize such symptoms could be somatic in nature given the stress that is inherent within my occupation but wanted to see if such signs and "bumps" are something that should be checked out. I appreciate any input. Thanks!
