I have found with MRSA the most important thing to eliminate pain and to promote healing is to get the boil opened up as soon as possible. The best, fastest and cheapest way to do this is by taking regular soaking baths in epsom salt. Also, take oil of oregano 2 or 3 times a day. I usually take 3 to 5 drops in a half a glass of orange juice. The juice masks the taste of the oil. I prefer to use DoTerra Essential oils as my trusted brand of oils. They have many other oils that you can use as well but Oregano has always done the trick for me.
