Good morning, few years I was involved in a hit and run car accident and I hit the ground with my face went to the hospitfalls hey told me they don't see anything wrong few years after I started having this other heavy painful headaches on the lower back of my head on the left. I was a very active person weight lifting. Now whenever I try to go back to my workouts I get dizzy and my head feels heavy always and whenever I try to shake it.
