Shaky and scary feelings. Me till date.

Hi , I wanna get a neuro opinion i have been to a neuro Psychiatry, they said it was anxiety, i had tests and its of abodomen and head, everything is normal, i hit my funny bone twice one day, since than i feel numbness in my last 2 fingers of left hand, but i think it has reduced, problem i am facing is when i put some kind of strain on my lower back like crunches etc i feel my back and abdomen is shaking, i feel like hot drops are pored on my head sometimes.i feel scared of some sounds, just today i felt popping like feeling on my right scalp. I also feel scared when i body produces unusual sounds.While i sleep at night sometime i feel my body shaking , the left hand index finger sometimes twitch towards thumb if i put stress on elbow.muscles just above knees twitch sometimes.And if i put weight on my left elbow my pinky finger goes numb very easily. I had a Lumber Spodyolisis , as i was coming back from gym , i felt instant weakness , and that scares me till date.
