I'm not sure what's going on. I have constant pain in my chest. Sometimes it's behind my sternum, sometimes dull pain on the left side behind my breast, sometimes it radiates through to my back. I'm 22 years old, female, overweight, but otherwise ok. I went to see the doc about heart palpitations about 1 1/2 months ago. She told me that she thought maybe i had anxiety so i started a prescription of Zoloft. I had a terrible reaction to it and quit cold turkey after 3 weeks. it made my heart palpitations happen so frequently i thought i was going to die. after i quit i had panic attacks for the first time in my life. that was almost a month ago. I have had my heart checked with echo, ekg, holter monitor, and blood work. the doc says my heart is fine but my chest still hurts everyday. I don't have heart burn alot, but i have radiating pain through my chest and it is worse at night. I don't feel hunger the same way either, it's weird like my stomach hurts when i haven't eaten but it doesn't feel like the same hunger pains i had before this whole zoloft thing. I have been short of breath and it kind of feels better when i press on the part of my chest that hurts. please if anyone knows anything about this i'd appreciate it so much. i have so much to deal with between my schoolwork, my children, and my husband. I really need to find a solution. oh and when i eat a lot i start to have irregular heartbeat with palpitations and tachycardia.
