Is the lump behind my knee a cyst?

I have a one half inch lump inside the back of my leg two inches above my knee (there is no visible mark on the skin). It is not painful or bothersome in any way. An acupuncturist thinks it is a cyst. If it is, what kind might it be, what kind of treatment might I get, and how necessary is it?


Are washcloths and other body scrubbers bacteria factories?

My question is about the cleanliness of loofahs and other body scrubbers. Since they usually hang out in the shower where there is constant warmth and moisture, wouldn't they grow bacteria? How often should they (scrubbers) be changed or how do you clean them? The reason I ask is that I am experiencing some hives, and the only thing I can think that is causing it might be the scrubber gloves in my shower.


Do cosmetics containing sunscreen provide adequate sun protection?

I was thinking of buying a face powder that says it has an spf of 30. It seems convenient to have a powder sunblock since lotions make my oily face greasy. However, I was wondering if this powder will even be effective as a sunblock since I heard that some moisturizers and other products that advertise an added SPF sometimes don't have a high enough concentration of sunblocking ingredients to make it effective. I would like to know what do you think before I make my purchase.


Where can I find the birth control sponge and what’s the efficacy rate?

1) I've always used condoms combined with a sponge for birth control. That worked well because if anything happened with the condom, there was always a backup — it made me feel safer. Then I get to New York, I go into three drug stores, and none of them have sponges. Now what? I don't want to rely on just condoms, I don't want to take pills because the whole hormone thing is rather frightening, and a doctor said that diaphragms make you more prone to get urinary tract infections, which I get frequently. So what am I supposed to do? What's up with this total absence of sponges?

2) In exploring other forms of contraception, what is the reliability rate of the "sponge"?
