Sounds like this maybe a situation you need to see a doctor especially if it has been 8 months.

Episode 66: A Front Rack Wrist Mob and More!

I have seen a doctor. I had an xray and they said there where no broken bones. I then had an MRI and they said their was a just some swelling. So they diagnosed me with wrist tendinitis. Do you think that it is possible that this wrist pain is being transmitted from a shoulder problem or elbow problem? My wrist range of motion is much more limited than the other wrist. When I get into a pushup position, I loose circulation to the hand. Almost as if something is blocking the blood supply. Do you think it could possibly be intersection syndrome of the wrist? Thanks so much!

What have you done to address the tendinitis?
The cause of the issue may originate at the shoulder or elbow.
You’ll want to start working with improving your wrist rom.
How is your power clean technique?
If your start position is unorganized this is an issue down stream at the fore arm.
What is your push up position like?

I have been taking fish oil. I have been working on my wrist range of motion a lot with a banded distraction. I have voodoo flossed my wrist and forearm a lot too. Every time I stretch out my wrist and forearm, the pain and mobility of the wrist is slightly better. But then in the next few hours the pain and stiffness comes back. My grip strength is unaffected by this. My clean form definitely needs work. I tend to receive the bar with too much with the wrist rather than the body. I have trouble getting my elbows up without sufficiently warming up and mobilizing. And that is the thing. The time I think I hurt my wrist/forearm or whatever is injured, I did not warm up and mobilize for the rack position. And the wod was for time so my starting position was most likely very lousy for cleans. As far as pushups, I think my form is okay for them. Thanks so much Kaitlin! I really appreciate it! 

It will take some time to hold the improvements for a longer period of time.
It would be beneficial to hit these items in the morning and at night. You want to have the area have the stimulus of the new/changed positioning more than once a day. This will help in the improvements lasting longer amounts of time.

Skill work on the clean will be important.
You may not be hitting triple extension.
Warm up is a key prior to any warm up. This needs to get worked out asap.
You need to include items that will get your body ready for the range you will use in the wod.
Have someone look at your push up form as there is transfer elements.
What loads first when you perform a push up?
