Hi. We can certainly continue after this if you'd like
Applying ice and topical capsaicin cream can help for now, but you really should have this looked at and get an x-ray of the hand since this may not be just a sprain of the finger. Sometimes there can be an avulsion fracture.
If it's just a sprain a finger spint and rest may be all that's needed but it would be prudent for you to have a doctor take a look now
