I have had shingles. At first I noticed the spotty like rash in a patch so I went to the doctors and they thought I had an allergic reaction to a spider bite. It wasn't itchy just looked agro. It wasn't until a few days later the aching started and I went back to my normal doctor who diagnosed shingles.
I was better after a couple of weeks but try and build your immunity.

Also You can't actually get singles unless you have had chicken pox. To put it simply, The chicken pox virus lays dormant in the spine and can come back out as shingles if you are run down and have a low immune system.

Hope you are better soon x
