Pain between shoulder upper back. Not!

Sep 2021 my upper back pain started with right hand pain and my lower back pain started with right leg sciatica. Consulted orthopedic doctor. He concluded some test Mri, hlab27 and many more and told me that i have ankylosing spondylitis  ( i didn't know about these diseases) although my hlab27 was negative. He prescribed me saaz 500 mg 2 times day. aceclofenac-sp 2 times a day folitrax 5mg once in week pan d ones in morning I took these med for 8 month with exercise and pain was vanished. In july 2022 when i get to know about AS little better. I have personally consulted Rheumatologist by concludibg some test, he told me that i don't have AS and tell me to stop the med. Till 10 sep 2022 i was fine. No pain continuing my exercise. But now i have started sharp but bearable pain between my shoulder on spine and when i rub my hand in upward direction i feel little pain on some vertebrae  with little right hand pain. Any suggestions pls, do i have AS or any other condition. Not
