I had a very mild case of shingles 2 years ago . It started with 2 small itchy patches on my left side ,upper torso . I thought it was spider bites , but the itching became extremely intense and wouldn’t go away . Then I developed sharp intermittent like stabbing pains all around the area where the rash was and my skin there was super sensitive. Went to docs and did a swab , definitely shingles . He prescribed me some medication but I cannot remember what it was . It still took a few weeks for the sensitive skin and the stabbing pains to go away . The rash actually took about six months to clear up and fade, but it wasn’t really itcy anymore . I can only imagine if someone had it all over their body it would be an awful terrible experience. Mine wasn’t good but it wasn’t any way near the worst, just 2 small patches .Thankfully though I made a full recovery .
