Cosochondritis caused by anxiety/stress?
A few weeks ago I had a panic attack followed by a few days of severe neck/head tension. Afterward, I felt good for about a week. Last week I woke up from sleep in a panic. I took my Visteral and was able to relax and sleep. The next day the tension was back but this time it was in my neck and arms. Four days later, I had a little panic episode and my throat and neck muscles got very tense. I relaxed but then I began to feel something in my chest, like gas pressure. Every morning since then I've felt normal but as the day wears on the pressure reoccurs. I had an MRI of my neck done last week & had to take several Xanax (prescribed and taken as recommended) and I felt great the next day. I went to the doctor on Monday but my results hadn't been read yet so I asked him about my chest (which had mostly just been an annoyance, barely any actual pain) and he pressed around and said it was costochondritis, nothing to be concerned about, alternate ice for 10 minutes then heat for 20. I was sore afterward and did what he said for the pain. I felt good this morning but after running a few errands this evening I began to feel a lot of pain. It feels like a giant bruise on my sternum. I can breathe fine.
After all of that, my question is: could this have been caused by my anxiety? The doctor asked if I'd been exerting myself but I haven't. I have a previous back and neck issue from a car accident and I already have a lifting limit so I try to be good. Also, I'm sure this severe pain is probably caused by him poking and pressing on it, but will it feel better or is it always going to be like this?
