hair fall.

Hi,
I have developed swelling and it is something like bacterial infection in my hair grown area. When if touch that swelling, i fell pain. Such type of swelling only developes in only hair grown area like head and eyebrow. I am losing over more than 50 hairs per day. And i rarely wash my hair because it scare me as it will lose more hair if i wash my hair frequently. Whenever i touch my hair it will surely make some hair fall as it came out sticking to my finger.  And i think if my hair goes losing hair at this rate then after sometime i will completely be bald. I m losing hair not only form my head but also almost all the body hair.such as pubic hair and eyebrows. Is there any connection with this swelling and hair loss. And it is not a natural hair loss. I can figured it at the hair loss rate. Before 8 months i had unprotected sex with a girl. Is there any connection with that, I hav consulted many doctors and it din't work. What shall i do.Its been over 4 months that i have started losing hair all over my body. I have used minoxdil 2% and it's not working. If i have to use some powerful minoxidil or any medicine to developed then i have to apply that throughtout my body since i also lose body hair and  it will be disgusting. Please advice.
