I get costochondritis quite regularly- inflammation of the sternum linked with ulcerative colitis arthritis but since having the cough cold bug that has lasted a month, I have a pressure pain in the centre of my sternum when I cough or lean forward. Do you think this is linked with the cough/cold or costochondritis, or could it be something else? It generally doesn't bother me during the day, moreso when I try and turn in bed or sit up from lying down. I'll see the doc next week but just wanted your opinion. Thanks!
