Its been about 2 months i have a burning sensation on my left shoulder blade. there is no itching or rash it just burns and the burning gets worse if anything touches it. went to chiro and no relief?

Suggest you visit either an MD or DO and have a proper exam of the area of concern. You could be experiencing what is termed notalgia paresthetica, a localized neuralgia over one shoulder blade, but this could represent a lingering area due to prior shingles. A chiropractor would not be expected to manage this.

It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. You may have frozen shoulder. It is treatable. It would be prudent to see a doctor, preferably a rheumatologist.
