There are two ways to look at your problems, one through symptoms and one thru existing pathology (C4-5).
You symptoms of “Numbness/Tingling in Both Hands”, “Lack of grip strength on left hand/wrist. Also noticed that left Tricep is considerably weak” fit with some disorders.
The left triceps weakness is typically due to a C7 nerve compression (C6-7 level) but you don’t note problems at this level. Triceps weakness can also be associated with pain inhibition due to the shoulder (you note “Left Shoulder Bursitis”).
“Lack of grip strength on left hand/wrist” can be from C8 nerve problems but again, you note no difficulties with this. Carpel tunnel syndrome can also cause grip problems and also cause “Numbness/Tingling in Both Hands”.
The C4-5 level can cause C5 nerve compression. See the section “Symptoms of cervical nerve injuries” to understand what this nerve can cause but it will not cause symptoms below the shoulder.
Leg symptoms will not be related to the neck (as long as you are accurate and there is no spinal cord compression).
