mine has done this before and it was infection . due from my sinsus
me too.. i guess it could be a scalp infection cause i have not sores on my scalp..
Sounds like raw nerve endings to me. Could be due to head aches, sores on the scalp, or even the start of the flu.
If it gets worse and you start to feel badly, see your doctor.
Do you have sores on your scalp? even just one sore?
Is it only one side? Shingles is possible,
Headaches (there are various types) is another possible cause. Plus, other things but those would be the first two. They should do an MRI if this does not resolve with treatment.
A Good Neurologist is your best bet to get to the bottom of what is going on,
