I just googled popping sensation in hand/wrist and www.mainephysicaltherapy.com said this: “The popping sensation, also known as crepitus, is frequently caused by a buildup of gas between joints, but it can also be related to tendons, ligaments or other soft tissue rubbing over bone. A common guideline is that popping sensations shouldn't be cause for concern unless they are accompanied by pain.” Since you have pain and whatever this is, is debilitating, I would suggest pressing the issue further and requesting a referral to a hand specialist to see if you can get a specialized look into the problem instead of just from a general practitioner’s stand point. They can miss a lot of things sometimes, I’d look into seeing a hand specialist. Hope your hand and wrist gets better soon!

I had a band or tendon get inflamed, and the only way to get it fixed was a release of the nerve by cutting it. I had dequervains synovitis. I never knew what it was nor could I ever pronounce it but I felt something snap in my hand and it was never the same. After surgery it is 95% better but I’ll have a day or two it’s off aka pain. I really hope you find the answer. I would just keep going to hand specialists until they figure it out.

I will definitely check into all of these and appreciate all your help I have a referral for an MRI and a specialist but don’t know when I can get in and I cannot work because it hurts so bad and I’m really starting to get stressed out about it sorry I didn’t see these sooner. I found a few things online but my doctor did not appreciate it ha ha Ha
