Promethazine Convulsion Causes and Reviews


Seizures are symptoms of a brain problem. They happen because of sudden, abnormal electrical activity in the brain. When people think of seizures, they often think of Convulsions in which a person's body shakes rapidly and uncontrollably. Not all seizures cause Convulsions. There are many types of seizures and some have mild symptoms. Seizures fall into two main groups. Focal seizures, also called partial seizures, happen in just one part of the brain. Generalized seizures are a result of abnormal activity on both sides of the brain.

Most seizures last from 30 seconds to 2 minutes and do not cause lasting harm. However, it is a medical emergency if seizures last longer than 5 minutes or if a person has many seizures and does not wake up between them. Seizures can have many causes, including medicines, high fevers, head injuries and certain diseases. People who have recurring seizures due to a brain disorder have epilepsy.

I got a Promethazine shot 4-5 weeks ago in my hip due to nausea and vomiting from a stomach virus. I now have a small lump-knot where I got the shot at and it is really sore still. I was told to massage it and put heat on it to make it go away but it doesn't help. Does this suppose to happen?
