I am 70 years old and I had the shingles vaccine 3 years ago. 3 week ago I had headache and pain only on the left side of my head from behind the ear to the top of my scalp, pain and sensitivity to touch. It went away pretty much, returns at times but not with such intensity. Now I think I have a few scabby areas, hard to see throught hair. I'm a pretty allergic person and have had two severe reactions to meds so if possible I use new agents only if necessary., and my PCP agrees. If my symptoms are now milder, do I need treatment? Also, someone in my household whom I am caring for has pneumonia,how infectious am I?
Thank you
