Thanks for your question on Health Care Magic.
I can understand your situation and problem.
You are having typical pleuritic pain.
It can mostly due to pleurisy (inflammation of pleura).
Most common cause for pleurisy is
lung infection.
Lung infection can be seen after upper
respiratory tract infection (URTI) like cold.
So we need to first rule out lung infection in your case.
So get done chest x ray.
If chest x ray is normal than no need to worry for lung infection. Possibility of
musculoskeletal pain is more.
Ibuprofen is anti inflammatory.
You will definitely improve with combination of painkiller and
muscle relaxant drugs.
Also apply warm water pad on affected areas.
Avoid movements causing pain.
Don't worry, you will be alright in 1-2 weeks.
But better to first rule out lung infection.
Hope I have solved your query.
Wish you good health. Thanks.
