I was given Tramadole for post traumatic surgery . I found the drug very effective .. However years later seperate incident i was given Tramadole and had a severe reaction to it . My heart was racing 1000miles per hr . I was in a car at the time , as a passenger . I ask the driver to stop the car because i felt like i needed to run run run .. I felt like Speedy Gonzalos for 6 hrs strait . Then as it started to subside i got the itchys head to toe .. I will never take Tramadole again . Every doc or hospital visit i make this very clear .
