There is a bump in my right ear on the back corner where the hole is to the ear drum. You can move it and it hurts very badly. I keep picking at it and which puss comes out of it. I cannot even put my ear buds in without it hurting. What is it and what do I do?

Basically it's a pimple inside your ear. My son would get them all the time. Best thing to do is take a Q Tip dipped in alcohol (yes, I know it's going to sting like mad) and daub the pimple and try and "dry" it out. It will probably take a week or more before this pimple goes away. In the meantime, other than trying to get whatever pus out of the pimple, there is nothing you can do to make it heal up or go away any faster.

Okay. What can I do about acne?

Acne is hard to get rid of. My son used silver water on a cotton ball twice a day on his face to kill all the active bacteria that causes acne and blackheads. It took him about a month and no more acne, pimples or blackheads. You can buy silverwater in health food stores or make your own with a silver water generator. Or you can use a zillion other "cures" for acne.

How do I obtain this SilverWater generator? Or build?

Use your search engine and put in Silver Water Generator. There are several different types out there to choose from price wise. You can make yourself one by using batteries but I found that a generator that uses the electric from an outlet gives much superior silver water. I bought one about 7 years ago for less than $100 and use distilled bottled water to make the silver water. I also bought a parts per million meter for about $25 off Ebay to test the potency of the silver water. I usually make a solution of 15-20 PPM and that works just fine.
