if it is not one-sided as you mentioned it is "something else" other than shingles but unfortunately without the ability to see it first-hand during an examination i would not be able to narrow down the many possibilities for you based solely on your description. you would need to see a medical provider so you can have these skin lesions properly diagnosed.
had pox in my 30's now 43 and have something similar. not localized in one patch. can shingles be more spread out? . it's mostly on my shoulders chest and back but also a few on my arms legs and now my hands. i have had a lot of stress lately. itchy burning pain. because it is not on one side of my body i think it might be something else stress related hives maybe?
