Thanks for posting your query.
Do you have fever/ cough with sputum/ sweating and squeezing sensation in chest?
Are you a smoker?
With the available described symptoms, there appears to be possibility of lower respiratory tract
infection with associated pleuritis
or muscular ache.
You should consult with internal medicine specialist and should go for thorough check up.
You should go for chest x ray
on preliminary basis.
Treatment depends on the diagnosed disease.
Meanwhile, you should take analgesics along with muscle relaxants.
