Hello and Welcome to HCM,
Thanks for writing to us.
It looks like tendonitis
. You can settle your tendonitis with appropriate physiotherapy
.You should perform specific flexibility and strengthening exercises to get your wrist and thumb strong and healthy.
Wrist and thumb exercises can help your wrist recover or can even prevent tendonitis from occurring.Even a few minutes of stretches or exercises per hour can bring comfort and restoration.
Hope this helps you.
Wishing you good health...
Dr Saurabh Gupta.
