I am a 63 yr. old female and had a fall in january2015 off my horse which caused a bad concussion and subsequent need for cervical fusions. I have always had neck and back problems and also breast cancer, followed by mastectomy. I have a lot of head pain, ,neck and shoulder pain, and have had more mri's and cats cans than I can count. I get regular massages and even massage my head myself as the muscles get tight and it helps alleviate the head pain. Today I felt the top left rear part of my headsoft spot was no and what felt like a bruise, and with further touch found a soft spot in my skull. The surrounding area felt a little swollen and tender. This oft spot was not there before! I'm sure! What is this?
