I would strongly suggest a visit to your primary care practitioner. Soreness after the Hep B vaccination (as with any injected vaccination) is to be expected however this has persisted far too long. This may me a bad reaction to the vaccine or the injection may have been given too far up on the Deltoid (shoulder muscle). A lot of women don't have a significant amount of muscle mass at that spot of the Deltoid, and directly under it is a pocket of fluid (called a bursae) that acts as a friction reducer in the joint. It is possible that when he/she administered the injection too high on the arm, he/she went through the Deltoid completely and punctured this fluid pocket. Which can trigger inflammation, pain and stiffness in that region. See your primary doctor soon and keep us updated!
