...anyone know what it could be? Have had stints put in recently with a blockage of 85%, 2 months ago. The other day I thought I was having the big one, sharp shooting pains going up in between my breasts. Hurt very badly. Lasted about 10 min then quit. Felt sore after. I had all the signs, clammy, sweaty, blood pressure drop, but when at hospital they said nothing looked like it was cardiac. So, see ya and sent me home not having a clue what to do next. Would anyone have any info what this could of been? Let me know if you think you could be of help.
