About 6 weeks ago, I became very dizzy in a store and just tood still unti it passed holding onto a shelf. two weeks ago, I tripped up a curb and feel to my right side just bruising my knee and leg. Last week, I had a migraine at work and took tylenol and was fine except for the soreness in my left side of my head. Yesterday, I tripped over the rug and again fell to my right side. Today, I have a dull headache on the right side of my head. Could there be more to this tripping of is it because I have degenerative disk and joint disease? (Had L5-S1 removed years ago)
