Yeah, we've all done it. Pop your symptoms in the Google search bar and see what turns up. Typically I will mistakenly conclude that I have cancer. Then the symptoms will subside and I'll forget about it, long before a doctor gets involved.
But I have a message for the person who stumbled upon my blog today via the Google search "lower back, intestinal, and taint pain" -- that is one unfortunate combination. I'm so sorry. You should probably go to the doctor.
Incidentally, I don't know whether to laugh or cry that my post about an acquaintance's terrible inflammation is the first result under a Google search for "taint rash."
