thankyou for your comments wishing you all success
Hello!
You should get an X-ray done to rule out fractures of your thumb.
Wear a finger splint for helping the healing process.
Take some NSAIDs such as ibuprofen to relieve your pain.
For soft tissue injuries get a tetanus shot done and follow up with a physician for a proper examination. If required follow up with a hand surgeon or an orthopedician.
Take care!
