I've been having what I thought was a mild bout of shingles on my left shoulder blade since December 2014, 7 months after starting Remicade. It started out with what felt like really bad muscle pain and a single strip of little water blisters running diagonally down my shoulder blade. At first I didn't put the two together. I thought I'd somehow pulled a muscle, even though I didn't recall doing anything, and I had some weird bug bites. After about 3 weeks I decided to call the doctor but by the time I got in the blisters were gone. I couldn't see my doctor and had to see the nurse practitioner. She said it sounded like shingles.
The pain eventually got better but I've been left with an awful itchy, tender, crawling feeling that's constant. Lately it's been worse so I went back to the doctor today, 16 months later, and he said it's a pulled muscle! He said there's no such thing as mild shingle or shingles without a rash, but I've found medical sites, including the Mayo Clinic, that say there is.
I don't know whether or not this is shingles but it sure the heck isn't a pulled muscle. And I don't have any dry or flaky skin to indicate psoriasis. It just feels like something is living under my skin and inside my muscle. It's much worse in the evening after I've been doing dishes and other chores. I just want to find out what it is and make it go away!
