I had a flair up of that while at a conference in NOLA suffered through it the entire week, plus picked up some strange bug bites. The ride back it Indiana was excruciating.
I went to our clinic for the odd bug bites, and had a Chiropractic appointment. Nurse practitioner heard my tale and didn't think those were from bugs. Brought the doc in- Shingles! went right down the sciatic nerve. Got a script and cancelled the chiropractic appointment.
All of that stuff I wanted. Glad it wasn't a thing I have to live with all the time.
