Not really sure if its shingels.... Is the pain from shingles muscular or deep skin or surface skin? I have pain in both arms still with no sign of rash. I reciently pulled a muscel in my side which is now also hurting. I have spoken to the doctor and have gone for blood work.
Go to the doctor as soon as possible. If it is shingles, there is medicine that the doctor can prescribe for you. The medicine, when given soon enough, helps to reduce any nerve damage. If you let shingles go, there can be a lot of nerve damage and you can have pain for the rest of your life. It is important to start taking the medication as soon as possible.
