The same thing happened to me last month when i got jabbed under my index fingernail after helping mum lift and divide perennial plants out of the garden.I treated it by soaking my finger in hot salty water for a few minutes and then treating with TCP ( or Lysol as you would know it as ).That cleans up the area and disinfects and heals the infection.
Make sure you are up to date with your tetanus injections, if not go to the Doctor and get a booster shot, and have the Doctor check your finger if you are worried.
If it has infection/puss take a needle heat it over a flame then puncture the puss pocket and drain it. Then clean the area with betadyne and then wrap it with a bandage. If it is just sore it will most likely clear itself up in 2-3 days. Just from experience. The following is from the pages of katy memorial pediatrics i do not claim or have rights to this information and neither does blur it- FINGERNAIL INFECTION DEFINITION •A large pimple at the junction of the cuticle and the fingernail •Redness and tenderness of this area •Occasionally, pus draining from this areaCAUSE Those with a large pimple or is draining pus are usually infected with the Staphylococcus bacteria. The bacteria usually enters the skin through a break in the skin caused by pulling on or chewing on the cuticle. If the cuticle area is only red and swollen, it is due to Candida (yeast). Yeast infections usually occur in children that suck their thumb or finger, swim a lot, or have waterlogged cuticles from other activities.EXPECTED COURSE With proper treatment, this infection should clear up in 7 days. If not, your physician will probably prescribe an oral antibiotic.HOME TREATMENT Antiseptic soaks If the cause is bacteria, soak the infected finger three times a day for 10 minutes in warm water and liquid antibacterial soap. Do this for 4 days, or longer if the wound has not healed. Antibiotic ointments For bacterial infection apply an antibiotic ointment 6 times a day. Cover it with an adhesive bandage. Continue to apply the antibiotic ointment until no signs of infection remain. Open and drain any visible pus pocket using a needle sterilized with rubbing alcohol or a flame. Make a opening where the pus pocket joins with the nail. If the pus doesn't run out, gently squeeze the pus pocket.
