Shahid Masoom first off rest it and ice the parts that are red or hurt. Ice 10 min at a time 2-3 times a day until the pain and redness goes away, usually for a week or 2. It takes about a month or a little more of a lot of resting it though. Use a splint. After the pain goes away begin to start heating it to promote healing Don’t do anything that can irritate it. Including phones, video games, typing. After a long month of resting, maybe a bit longer, then you could slowly start using it again. Slowly start building strength. These exercises in this this video are only after the long month of resting. It might take a bit longer to recover if you use your thumbs Often. Took me about 2 months.

Hello Shahid Masoom, is your thumb better now? I hope you can use it again.
