Thanks for posting your query.
From description it seems you might having ligament injury
or triangular fibrocartilage
complex (TFCC) tear at wrist. The TFCC is a major stabilizer of the distal radio-ulnar joint. These ligaments support the joint.
I suggest you to consult an orthopaedician nearby for a detailed examination of wrist. You may get the X-ray/ MRI
of the area affected under his/her guidance to reach the proper diagnosis and treatment plan according to that.
Wishing you good health
