I recently fell and hurt my knee now when I cough or spit it hurts just below my rib cage on both sides  <response>: Hi. Thanks for your query and an elucidated history. You have a typical history of fall on the knees followed by pain bellow the rib-cage if you cough or spit. This has happened due to the muscles of the upper abdomen start from the lower ribs, and it looks they have got sprained a lot while your body tried to balance the fall. I would advise you the following:Take a full bed rest. Take anti-inflammatory medicine like Ibuprofen at 8 hourly duration after food and with Sanitizing. Apply a rubrafacient liniment locally. You can apply an elasto-crepe to the lower chest to support the movement of the ribs. Take laxative to avoid constipation. Let the room be warm. You will be fine soon.
