I am going to Cambodia on November 3rd on a mission trip. On Sept 20, I began my series of required vaccinations. I received the Hep A and B vaccines that day. About 4 hours after getting the vaccines, I began having pain in my right shoulder, collarbone and down my right arm. I still have pain in these areas, sometimes mild and sometimes moderate to severe. In the last week I have developed pain in my right jaw, temple, ear and the right side of my neck. Is this the result of the vaccines. I m starting to get concerned.
