2 days ago, I felt a quarter-sized lump on the back of my skull, left side, just above the bottom bone, then yesterday, there were 3 more small ones underneath the quarter-sized one and now today, there is another lump on the left side of my skull just above my ear. They are a little sore to touch, not really itchy...it sometimes, throughout the day, feels like a neck strain when I turn my head, but it is the lump that is strained....I m 63 years old in March. I ve been taking ibuprofen and even tried regular aspirin. OUCH!!!!
