Hello, I m 27 years old I ve been having chest pain for long time now I ve gotten ECG, blood test and x-rays but everything coke out fine, what I don t understand is why my symptoms are getting worse, I feel pinches of short pain in my chest also tightness, get dizzy when I get up, muscles twitching, pressure in my head not like a head ache, blurry vision, tightening of jaw, a lot of goosebumps like every 10-20 min., cold sweat and I feel confuse sometimes, I also feel the twitching in me head now....... I think I could be some type of poison or coronary disease.... but i don t know that s why I m here..what can it be??
