I am 29 and currently diagnosed with Costochondritis & take celebrex. Is it normal to get short of breath at different points during the day. I sometimes will get short of breath during the day, but usually become more short of breath when driving or going to sleep (sometimes catch my breath). Also, is there any rhyme or reason to when the pain will come and go. I could think of a couple days when i may have lifted something that aggravated it, but yesterday, i just walked around the carnival (having a bad pain night). I alternate heating and ice packs. I have a stong family history of heart disease and keep questioning if something else is going on that the doctors are not seeing. (I don't understand how my bone scan would say "no evidence of costochondritis" and still have the diagnosis from my doctor & how i have a mobile interatrial septum and that doesn't affect this). I can't get into a cardiologist for a couple of weeks and my rheumatologist appointment is not until the end of the month. Do you have any suggestions or can you shed some light on my symptoms.
