I just read this "I have soft tissue swelling in my thenar eminence and discomfort at the base of my metacarpal with “squishiness” with thumb rotation. I am hoping this goes away." while massaging my swollen left hand - I way overdid things yesterday without a splint or brace, and am paying today, 12 month post-op with a little discomfort...
The right hand, done 3 years ago, and equally abused yesterday, is fine - so most days I am fine, but occasionally the newer one complains, so I guess healing is not yet complete.
Good luck on continued healing.
PS, I had my hard splint cut down to wear for heavy work in the yard and house, and wear a soft one for biking, repetitive motions, etc sometimes.
