In an effort to help I borrowed this from another site hope it helps.

General Treatment for All Cuts, Stings and Venom Events:
Cleaning
The first order of business. Is there any foreign material in the wound? Can/should you remove it? Many types of wounds are best flushed with clean warm water initially. This flushes away debris, and makes the area easier to inspect. With invertebrates (e.g. sea urchins) the careful use of forceps might be called for. Take care to not cause even more damage. Many stings and barbs are brittle and crush easily. When and where there is much pain, swelling or residual material, get medical attention.
What did your mom advise? "Wash up good with hot soap and water". Good advice. This simple procedure effectively cleans most superficial wounds sufficiently.
Disinfect:
The wound and surrounding area should be de-contaminated, freed from chance of outside organisms or poisons. For aquarium cuts and bio-punctures the above recommended use of hot water and soap will do; but you may want to employ more thorough cleansing with peroxide, an alcohol or iodine solution or other commercial preparation.
Maintenance:
Two words keep the wound dry and clean, and a short sentence, "keep your eye on it". Does it hurt, is the wound emarginated? This is good to some degree; an indication your body recognizes that something is going on and is reacting to it.
Treatment:
Depending on the direct cause(s) of the wound ongoing therapy might include anti-inflammatories, some form of pain-killer, antibiotics and more.
Overview:
Infection occurs when bacteria enters the body through an open wound or abrasion. Over a period of time a sore or swelling may develop. Given time, most of these will remedy themselves without treatment. Cleaning, disinfecting and keeping the wound dry and covered will speed up the healing process.
Should you have doubts, persistent pain or swelling for any length of time, I suggest you seek medical help
