What Causes Neck Pain Radiating Towards Shoulder Along With Numbness In Hands?

hi, I have had neck pain at the base of the skull, radiating down the shoulders, back and up into the head with shooting pains, both my hands have been numb for months, now my left foot is going numb, i ve had mri done to the neck and head, aside from a slight cervical stenosis, they can t find out what s going on. When unrinating, it takes a long time to get it to start and i have to be completely full. My energy is non existant, when waking I can barely move and i m on a bevy of medications. I ve always been the one that can never sit still, now I can t do anything. I m a caregiver to my dad who is at the end stages of dementia, so between caregiving and my body feeling like it s falling apart, my mental state is being overly effected. I dont know what to do next
