If it is just some sort of bacterial infection on your skin, it might be helped by bathing in a warm bath with a few drops of Oil of Oregano. For example, if it is something like a staph infection, you could bath in Oil of Oregano as well as ingest some using capsules or just a drop or two diluted in water.
Hopefully, MH might have more options but you may have to give more information if you remember what triggered these episodes.
Also, you may consider doing some liver flushing since your skin is obviously being used to process toxins perhaps because your liver and gallbladder are too congested to handle it...
