Looking good!
I hope your your husband is now on the mend!
My sister had the same problem with her hand. She got a cut several years ago, the tendon slid down. The first fix didn’t work, so she had to have it redone this summer. Then in October her PT noticed some red lines and walked her over to the doctor’s office. They had to do a third surgery to clean out the infection and she is still having to inject antibiotics into a port on her other arm.
