hi I am feeling chest pain in the left & middle of my chest..on & off but, at least once a day for the past 2 wks. Tonight it has happened but I feel hot & then very chilled but , also feel nausea. I have no medical insurance.Have been under stress lately after being dianosed as having melanoma for a 2nd time but, different body part. I have had over 41 surgeries so far in my life. These pains are scaring me but, don't need anymore medical bills right now while trying to pay for my cancer surgeries. I had 2 so far in the past month & another one for next week. My pain has subsided a little. It seems to be lasting longer each time. Thought maybe a blood clot or something?
