Numbness In Back of head and top of head and Whole top teeth

Hi im 19 and I work in a warehouse and I had to do a different job so i went to a new station and I had to sort of stand up straight and moving my head and neck to the side and the other side and looking up and down etc in an unusual position sort of like sticking my neck out while looking up because there was like a glass disc that was near my head so i was caution when i walked and i was in that bad position for like 5 hours straight.

and clearly that same day ive noticed my head was getting numb.

That was 2 weeks ago and now its like non stop numbness in back of head and top of head and whole top teeth.

if i touch my jaw or face or forehead or anywhere on my head and even if i massage my neck that numbness gets worse on head and whole top teeth.

Need help on this.

Thanks.
