I have been having real bad neck and shoulder pain . It started with my neck and it felt like I slept wrong . I went to the Doctors and he said I pulled my Trapeze Muscle . He gave me some muscle relaxers to take and said to use Ice pack / heating pad . It has been a month now and it's not any better . But now the pain from my neck runs down into my shoulder. It feels like a deep stabbing pain in my shoulder . It also feels like pins and needles or tingling in the top part of my shoulder . I went to the Doctor Friday he did X-rays of my neck and shoulder and blood work. He doesn't know if it's my Sarcoid so I've got to go to the Lung DR next week and ask him . If the lung Doc doesn't think it's sarcoid related, then my Family Doc is going to do a nerve test and MRI to find out whats going on. I've also been having a lot of joint / muscle pain in my other arm too. Could it be Fibromyalgia? I just don't know .
