Elbow pain - is this tendonitis?

I have fairly recent pain in my left elbow.  it is unusual to me.  It is almost like the point of the elbow bone itself hurts.  I can rub that area hard and get some discomfort.  It hurts some with a pressure feeling when I fully extend the arm and push for hyper extension (if you get that).  I get some minor pressure pain when doing tricep pushdowns, but not during bench or rows or deadlifts or curls. (my main exercises right now).

There is not really any pain up the tricep nor down the forearm.  Oddly it seems to be better if I try to 'crack' the elbow with full extension, but sometimes that just hurts and it doesnt 'crack'.

All in all, many of my joints hurt lately and feel the need to 'crack' them (ankles, wrists).  But this elbow is the main issue.

Again, doesnt stop me from working out and I am not pushing through pain either.  More after I workout in everyday duties.

** I will just add now, it does hurt just above the elbow bone on the back...which I would imagine is the tricep tendon...

Thoughts?

the only one qualified to determine whether its tendonitits or not is a doctor. i would say ice and heal, give it a week off, and if you still get the aching/pain/popping go see a doctor

first day with no buds, 11/17, need a new job. 1 down 13 to go.

i wud say it probobly is. i have tendonitis in both of my knees, and in my elbws, and what u have sounds just about the same. but it should only hurt badly if you are doing something that puts allot of pressure on the joints. like for me, my elbows hurt if i do tricep extension on a machine. with my knees, sometimes it hurts goin up stairs, but not that bad..
