Within an hour of the injection I suffered a headache which progressed to a severe migraine headache. I also experienced very high blood pressure and broke out in sweats. The blood pressure did not begin to normalize until 5 days and I am still experiencing a headache (although not a migraine. This is the fifth day after the injection. I was not aware of any of these side effects so I was hospitalized due to the extreme blood pressure and extreme headaches. A cat (sp?) scan and spinal tap was done in an effort to determine the reason.
