was golfing when i took a swing i felt a bad pull or pop, felt like a pulled muscle. i rested for about 3-4 weeks. then i tryed to play softball, but  took it really slow, until i had to run, when i ran full speed felt like some shot me in the side and now it feels worse. only huts me when i sneeze or cough, also when i am on my back and roll to my left it is really uncomfortable and sometimes hurts...??? muscle or worse?
Thanks for your question on Chat Doctor. I can understand your concern. Possibility of musculoskeletal pain is more because you got this while playing golf shot. And your pain is also associated with specific movement (bending) and coughing and sneezing, so all these also favor musculoskeletal pain more. In my opinion, you should do following things for better symptomatic relief in musculoskeletal pain. 1. Avoid movements causing pain. 2. Avoid bad postures in sleep. 3. Avoid heavyweight lifting and strenuous exercise. 4. Sit with proper back and chest support. 5. Apply warm water pad on affected areas. 6. Take combination of painkiller and muscle relaxant Chat Doctor.  Don't worry, you will be alright with all these in 1-2 weeks. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
