I have been experiencing sharp pains throughout my body, particularly in my chest, left side of back, left leg in calf & shin. rib pain on right side. also i randomly have difficulty breathing. I've seen multiple doctors also i have gone to the ER thinking i was having a heart attack. Test's iv'e had done are EKG, blood work. physical exam's not entirely sure what the blood test tested for, but my doc said liver, kidneys, & all other organs where okay. I also get light headed & feel like I'm going to pass out. They keep telling me nothing is wrong. but this has been going on forever. I went to a therapist that determined i do not have anxiety issues. so i don't think it's heath anxiety. If anyone has experienced these symptoms & has any idea on what might be going on with me it would be so much help. this has been going on for four months now. i constantly am in fear that i will die form my symptoms.
