Mystery Virus?

Patient: This started with a headache that lasted 1-2 days. Then extreme lower back pain, 1 day. Sciatica down my left leg for 1 day then a raging fever for 24 hours. When the fever broke I had blisters for the first time in my life. The symptoms have improved greatly but I’m still tender in my lower back and lympnodes in my stradle. I’m a 46 year old construction worker with no lifestyle changes and I’m in decent shape.
