How old are you still getting hand-foot-mouth disease, minus the mouth because you don't want to post your face on the internet LOL

Kidding, get well soon.

Keep in mind the test are not 90% accurate, but a good suggest by Mr.Docter on where to start.

His problem is ingrained over long period of time. So your quick fix with vinegar will not see the effects like how you did. Anyway, thank you for sharing. Good to see the doctor declare his specialisation as a chiropractor.
