Costochondritis Pain that comes and goes within minutes?
I'm 28 years old, male who is in average condition. A couple of months ago I was diagnosed with Costochondritis, most likely due to being at an office job where I sit for 8-10 hours a day.
Anyways, every couple of months or so, I'll get a flare up and be miserable for a couple of days before it fixes itself. However, something I noticed that was extremely weird last night.
When I get the pain, it's not always super bad, but last night it was a sharp pain, like someone pressing two fingers as hard as they could against my left breast-bone/sternum area. While it was flaring up, if I even touched it a little bit with some pressure on a certain spot, it'd send pain through my chest with how sensitive it was.
However, after laying down and trying to get comfortable, after about 5 minutes, the pain just stopped. Went away completely. I could press on the same spot with no pain whatsoever.
I woke up this morning and it's stiff where the pain was, but no where like yesterday.
What I'm wondering is, is this normal for Costochondritis pain? Is it a muscle that is spasiming out that causes the sensitivity and would it just vanish suddenly like that? It was defiantly apparent when I touched the specific area on my sternum that there was shooting pain, but for it to just go away is strange.
Note: I've had this happen several times over the years and usually after about a week it clears up, so I'm really confused.
