Welcome to BYC.
So sorry about your injury. Rooster spur wounds have a high chance of infection and may require oral antibiotics or other treatments that need attention by a physician.
@duckets advice on a tetanus update is important, a puncture wound by a spur is a high risk wound and if you have not had a tetanus booster within 5 years, get one as soon as possible. Keep it clean but don't apply neosporin or ointment topical treatments, if it needs to drain let it and don't seal in bacteria. Try ice packs to see if they help with the pain, if not, try warm compresses. Take oral Tylenol and/or an aspirin related over the counter pain reliever - whichever you tolerate the best - until you can see or talk to your doctor.
Once you are better, consider doing something about those spurs. I think you can trim or file them.
