funny enough I did overhead tricep extensions just yesterday

4 sets of 10 reps with 16 pounds.

When I was looking at the muscle in motion, every time I extended it fully the bulge of the muscle was about 3 inches away from the elbow, from there do you actually start seeing the tricep.

My triceps also hurt the most when I work them out, even now I feel a sharp pain when I ever I do the motion.

Get some some resistance bands, it's a lot easier on the joints and they're relatively inexpensive.
You're triceps might insert higher than avg, I can't really tell without seeing it though sxb.
I'd focus more on pressing movements for now, you need to strengthen and grow not just the muscles but the actual tendons as well.
