Pains after vaccination?

Hi I will soon be entering medical school which means that I am required to have a few shots before I can enter. About a week ago I had a combined tetanus/diphtheria shot with no real side effects. However 2 days ago I got a shot for both MMR and Hep A/B (combined shot). For the past 2 nights I have not been able to sleep because I have been having localized pain in my joints and neck which inhibits me from getting comfortable and falling asleep. Could this be a result of the vaccinations? And if so when could I expect the symptoms to end, and in the meantime are there any medications I could use to aid in with the pain/sleep.
