Back in my "wilder younger days" I fell asleep by a swimming pool--woke up couple hours later...When showering and shampooing I noticed two swollen "objects" on my scalp--ticks"

after removing them I applied some antiseptic...but lo, the next morning my entire back of head had horizontal rows of swollen lymph glands...also broke out with a "rash"--Doctor put me on some antibiotics, fearing a rickettsial type disease...evidently, according to Doctor, the head has lots of lymph glands for our protection.
