Shoulder pain, it's like between two bones. It hurts when I breathe, big breath = big pain as if something is poking me. Not muscular.

Based on your description of the pain you are feeling in your shoulder, it sounds like it could be related to inflammation or a possible rib injury. Taking an anti-inflammatory medication may help reduce the pain and stiffness. If the pain persists after taking the medication for 7 to 10 days, it would be advisable to see a doctor to rule out any fractures. When there is pain in the ribs or intercostal muscles, breathing can exacerbate the discomfort. If needed, a prescription for an anti-inflammatory medication can be provided to help alleviate the symptoms.
