Hi Doc's, My Name Is Christopher. I Am In Constant

Hi doc's, my name is christopher. i am in constant pain.back in approx: 1994/5 i injured my back while lifting small packages did not go to hospital that day i finish work went home. The next day could not walk upright i was in bad pain.i went to the doctor and was diagnosed with a strain lumbar. My back has been hurting every since, i have been to the doctor on several different occasion's for complication's of pain in my lower back.Bonus question i was given an hepatitis b vaccination(1998) shot for a job working in an recycling company, i have severe pain in my upper left arm where the injection was given. Can an hepatitis b vaccine cause ongoing pain(in the injection area) for this long until this point?
