Thanks for posting your query.
Do you have cough with sputum/ fever/ breathing difficulty?
on right side may be due to underlying lung parenchymal involvement (pneumonia), muscular pain
and neuropathic pain
You should consult with physician and should go for chest x ray on urgent basis.
Lung parenchymal involvement can be detected by chest x ray.
If chest x ray is normal then you may have muscular pain or costo-chondritis.
In such condition, you should take analgesics with muscle relaxants.
