Yeah, I can relate! I just recently had a bout with Lyme's Disease(or some similar tick-borne ailment--they are all easily treatable with the fairly cheap antibiotic Doxycycline)--and it was NO FUN! TERRIBLE joint pain, as well as lethargy like- yet unlike the flu. I was diagnosed by one doctor as "just getting old"(many doctors in the Southeast are rather ignorant of Lyme's Disease, or reluctant to diagnose it because the damn insurance company mafia won't pay for it!), and my blood tests for Lyme's kept coming up negative, as apparently 90% do when you've had it awhile(as I had)--so far there are no really good tests(I looked all this stuff up on the internet--an excellent site is "Carolina Lyme"). But the treatment is cheap and easy, and luckily I went to ANOTHER doctor who suspected Lyme's right away and put me on the antibiotics which eliminated the debilitating joint pain(mine was mostly in my right knee and hip joints) and lethargy ALMOST IMMEDIATELY, and the symptoms(so far, knock-on-wood) haven't come back. It IS probably a miracle I've only now contracted my first tick-borne disease, as many ticks as I pull off myself roaming the woods all the time as I have for decades! But this crap is nothing to ignore(which is easy to do at first, because the symptoms come and go), so I advise everyone to BE AWARE--Lyme's disease is EPIDEMIC now!
