Yesterday I was sitting on the sofa and when I turned I felt a pain in my chest underneath my left breast. It has got progressively worse since and when I breathe and move it is excruciating. I am putting heat and taking painkillers but every breath hurts and any movement or coughing. What is it ? That area feels like its pulsating
Thanks for your question on Chat Doctor. I can understand your concern. Since your chest pain is associated with specific movement and posture, possibility of musculoskeletal pain is more. So follow these steps for better symptomatic relief. 1. Avoid heavyweight lifting and strenuous exercise. 2. Avoid movements causing pain. 3.  Avoid bad postures in sleep. 4. Wear rib belt to prevent mobilization of painful rib area. 5. Better to take combination of painkiller and muscle relaxant Chat Doctor.  6. Apply ice pack application on affected area. It will be more beneficial than warm water pad. Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
