I'm 5 weeks post diagnosis but still awaiting an mri. I just wondered if anyone else during recovery suffered with short, sharp chest pains. oddly they seem to start on the right of my chest or from down my right arm/armpit, occasionally they come from my bottom jaw . my upper back feels very tight and achey all the time and this radiates into my ribs. it's starting to really irritate me and there seems to be no particular time that it happens.
