What Causes Constant Pain All Over The Body Upon Movement?

2-3 months after shifting to new home and new office, I started getting pain in my shoulder and back. If I strech my neck or back then there is pain. I waited for another 4 months and since it was not getting cured automatically, I consulted doctor. He asked to get the tests done for Calcium, Thyroid, Hemogram, Vitamin D, Vitamin B12. All other test reports were normal except Vitamin D (8.65 nmol/L) and Vitamin B12 (125.2 pg/mL). Doctor prescribed Toyo 60K and Matilda forte for 3 months. After that, both, Vitamin D and Vitamin B12 levels were normal. Vitamin D (51.5 ng/mL) and Vitamin B12 (263 pg/mL). But pain continued. I again consulted doctor and this time, he asked to get the RA Factor and ANA-IFA tests done. Both the test reports were negative (normal). But pain is still there. He has now prescribed Etoshine 90 and Sarotena 10 mg for 20 days and asked me to meet him again. I am taking these medicines from last 2 days. I am not able to understand what disease I am suffering with and how it can be cured. Pain is there in all over body. If I strech my hand or leg then there is pain in that hand or leg. If I strech back a littlebit then there is pain. If I move my head left then there is strech in right soulder and therefore, I feel pain there. Similarly, if I move my head right then there is pain in left soulder. If I strech thigh then there is pain in thigh also. Please help me. One thing I observed that like all others colleagues in office, I also have to sit under central AC. And I do not like to sit under AC because I feel too cold. But doctors do not think this as cause for the pain I am suffering with. Please help me doctors. It has been almost ten months now but pain still persists in my body.
