I had a knot at the back of my head and thought it went away but it appears that it has moved to the right front side of my head. I haven t hit my head and it only hurt s sometimes but mostly itches. I also have headaches but, I m wondering is these related or what these lumps are, and where could they be coming from and/or is this something serious I need to worry about? I m 68 years old, A retired school teacher with numerous illnesses. Unknown anemia , COPD , Diabetes, Heart murmur, Hypertension, angina .
