Pain on top of wrist especially when bending forward

Last Friday (4 days ago) my left wrist started feeling sore & stiff - I can't remember if it hurt right when I woke up or later in the day - I have never had a wrist injury in either wrist & this wasn't brought on by a fall or any traumatic event, but I HAVE had a couple ankle sprains in the past & from what I remember of those sprains the pain is very similar - just in my wrist instead.
-Limited range of motion & pain in wrist.
-Painful to weight on.
-No swelling that I can tell.
-Tender to touch on top/back center of wrist, directly where joint bends - doesn't seem to be "mushy" or hard anywhere compared to unaffected wrist.
-No pain when grasping things or weakness in grip, but pain occurs if I try to lift the weight of whatever I'm holding.
-Sometimes pops/catches/cracks on the top center of wrist - if I move wrist in a circle a couple times I can usually get it to do this.

Location of pain:
-Center back/top of my wrist, directly where my the joint bends.
-Had been radiating toward & around thumb before I started periodically icing wrist & taking advil throughout the day (which I started doing yesterday) - icing & advil hasn't seemed to help pain on top/back of wrist

Pain made worse by (in order from most pain to least pain):
-Bending my wrist down/forward (like if i hold my arm straight out with my palm down & bend hand so it becomes perpendicular to the floor)
-Bending wrist up/backward
-Bending wrist out/toward pinky finger
-no pain bending wrist in/toward thumb

Realized this morning it is definitely more stiff/sore in the morning, but not a huge difference.

any ideas?
