Hello. Welcome to HCM.
The pains in lower cervical and upper back point out towards spondylosis or mechanical musculoskeletal pain
. It is important to have MRI of cervical spine
and accordingly go in for guided physiotherapy
. As a preliminary step make sure your posture is correct.
Secondly dry cough with low grade fever
, if has been long standing warrant investigations such as X ray to rule out tuberculosis.
Hope this helps.
