I will tell you my story and see if any of it matches yours.
For a long while I have had on and off chest strain like pain, I have always put it down to strain through lifting or exercising, despite there being a lump over the sternum ( i thought it was just part of my build)
Anyway, 2 weeks ago I got concerned about this lump as it hurt when pressed and I had had this strain like pain for 2 weeks, so I went to my doctor.He thought it was a fatty lump and refered me to see a surgical doctor, which I did!
He thought it was degeneration ( arthritis) and sent me for an x ray. The x ray chap said the same, but is sending the x ray to the surgical doctor for him to have a look........thats the story so far! I am hoping to see the doctor next week.
The pain I get is worse when I am laying down and I have to hold my sternum when moving in a flat position.
Is any of this relevant?
