Thanks for your question on Chat Doctor. Your symptoms like chest heaviness and strain especially after carrying things by right side, are mostly due to musculoskeletal cause. But better to rule out pulmonary causes first. So get done chest x-ray.  If this is normal than no need to worry. Your symptoms are mostly due to muscular cause. Try to follow these steps for better symptomatic relief in muscular pain. 1. Avoid heavy weight lifting and strenuous exercise. 2. Avoid bad postures in sleep. 3. Take good painkiller and muscle relaxant. 4. Apply warm water pad on affected site.
