By the way, some six days ago I got a feeling of a kind of tingling pain on the right side of my scalp, and when I brushed my teeth I felt pain in my gum on the right side. I didn't think much of it at first, but yesterday I got blister in my scalp as well so I went to see a doctor today, and it turns out I have shingles. So now I'm on valaciclovir, the pain isn't as bad as I thought it would be though.
Good thing you caught it early! Hopefully it doesn't progress any further.
Under a lot of stress lately? I'm not a doctor but you should consider bumping up your vitamin D intake with supplements if necessary.
