I got a Hepatitis A innoculation in the right arm on Monday. On Monday evening, my left arm below the elbow had swollen up to twice the side. It was strangely just a small area, about the side of 7 inches long and 4 inches wide. Went to the doctor who gave the injection, my internist. He said it was tennis elbow. Went to the orthopedic doctor - he said no way was it tennis elbow, it must have come from the injection. Two days later it is still swollen but not as much. Anyone else have any knowledge of such a side effect? Other than that I felt sick, like I was coming down with the flu with chills. And my heart beat faster than normal and I couldn't sleep. Thanks for any insights.
