Wrist locking up

About a year ago, I developed tendonitis in my wrist after having a baby.  Shortly after that, my wrist started locking up.  It locks up at an angle bent towards my thumb.  This happens every night and sometimes during the day.  I have to physically "pop" it back into place.  It isn't painful when it locks up just really annoying.  The extreme pain comes every morning when I push it back in place.  I have been to an ortho.  They did X-rays and an MRI.  All they found was the tendonitis.  About 6 months ago, I had to take prednisone for an unrelated injury and that cleared up the tendonitis as well.  I am still left with a wrist that doesn't work properly.  I have tried bracing, anti-inflammatories, and different exercises.  My ortho has given up.  He doesn't know what is causing it.  Any ideas?

Hello,

With no injury to any bone confirmed by an X-ray it sure it is a tendon or ligament problem. You try doing physiotherapy and strengthening your tendon under a physiotherapist for a sustained period of time.

If it does not help follow up with an orthopedician.

Take care!
