I have been suffering pain in left n right sides of chest. Like a stabbing pain, not high but making me uncomfortable n frightening. The pain spreads from left side to left arm lightly. N my pulse rate could be felt as if its racing. My 2d echo cardio, ECG, TMT reports are normal. Also i was diagnosed for anxiety disorder and when ever i stop taking nexito plus tablets i would get this pain and feeling with increased anxiety levels and hissing sound inside ears. Are these any side effects of tablets or symptoms or abrupt withdrawl from using nexito? Also im having pain in the abdomen on d right side near liver area. My endoscopy shows no positive signs, n my ultrasound scan is normal too. My doctor advised me to go for CT SCAN ABDOMEN. Is there something serious about my body?
