I Have Recently Been Diagnosed With MRSA. It Is In

I have recently been diagnosed with MRSA. It is in my nasal cavity due to a nasal ulcer from Lupus. It is my understanding that there are two main antibiotics that kill the infection, doxycycline and I can't remember the name of the other one. I am allergic to both of the antibiotics but am giving the doxycycline another shot. It also have a lesion under my right breast. It is about the size of a dime. The doctor also gave me an ointment to apply to the area three times a day. I am a believer in essential oils and would like to know what you might recommend? Lemongrass, oregano and grapefruit are oils that I've read about. I also have a cough with mucus. Two family members have raging colds, I only have the cough. I cannot afford the $15.00 right now. I am disabled by my Lupus and my husband doesn't get paid until tomorrow.
