The top two possibilities that strike my mind are that you are either:
1.) Having a bad reaction to something, ie medication reaction--many medications have your exact symptoms in their list of "warnings of severe reactions." I won't bother typing specific meds on here, since there are myriad, but if you have started taking any new meds shortly before your symptoms appeared, that definitely could be the cause. If so call a doctor immediately and stop that med!
2.) Contracted an infection, and a nasty one. HIGHLY commonly overlooked, misdiagnosed and mistreated are infections which can be caused by tick bites. Go to the Tick Borne Disease Alliance website
the Centers for Disease Control home site
and the International Lyme and Associated Diseases Society site
You can type your symptoms into various search engines (google, ask, etc) and see what pops up. Babesia and Anaplasma are two organisms, commonly transmitted by ticks (but not only ticks), which cause some of your symptoms. The websites I listed above are great resources and I recommend reading through any information they have. There are many nasty infections and what you have sounds serious. Don't let the medical community push you around like I have:
I live in CT, the "state of origin" of Lyme Disease, and yet I can NOT get ANY medical treatment for my symptoms, which I am almost convinced is disseminated Lyme Disease with a smattering of Bartonella. You would really start to think doctors have been allowed to get their degrees out of a Cracker-Jack box, and that their ethics are simply nonexistent. I have been sick for many years on and off, worked through it until last September when I got symptoms similar to West Nile (which may be what it was)--one ER visit during a seizure (never had one of those before) and they merely gave me a CT scan then dumped me out with a recommendation to see a neurologist--none of those take my State insurance. Yeah I'm too broke to afford an HMO like you are, self employed and all of that. Couldn't even get into a doctor for weeks, 6 months to see a specialist--now I seem to have permanent damage to my spine and CNS (including herniated discs in mu neck and back, persistent neck tremor, spasticity, and weird vertigo spells to name a few). I'm only 35 and I have a 3 year old son. It's like my life is over--I can't perform my job any more, I can't even figure out what kind of work I COULD do since I have erratic symptoms flare-ups, I can't get medical treatment, and I'm lucky I am well enough to care for my son (I wasn't at all for quite a while).
I have been told that if you do your research, come in ARMED with prewritten questions, printed data, and keep logs of your symptoms, you can eventually be forceful enough to command a doctor's attention and get diagnosed, and treated. Although it's frightening that you have abnormal blood results, at least it's hard physical evidence that something's screwed up, and someone should listen.
I hope you are ok and find the help you deserve. Good luck and best wishes! -t1cked off in CT
