Misshalf! I'm so sorry to hear that you're struggling. What a crappy holiday season!
Yep, it sounds like you totally have CFS. I'm sorry.
I have "post west nile syndrome" that has very similar symptoms to CFS (but it has some nerve stuff on top). I've been getting every little flu that has been going around too, and this season it looks like the viruses floating around are fierce!
And, the PMS severity...have you been tested to see if you were exposed to West Nile while all this was going on?? Severe PMS/menstrual pain is a very common lasting effect that us West Nile ladies have. I am flat on my back in pain for atleast three days every month now and then my body has to recouperate from the energy used after that.
There is another factor that can severely effect PMS...thyroid. That's pretty easy to check with a blood test. If your thyroid is off, your cycles can go from being really mellow to monstrously evil.
When I first got sick, my doctor in Colorado started to look for the underlying reasons why I got so sick in the first place. For me, my thyroid was off and they found that my adrenals were really really close to being permanently ruined...and he told me no more work and to just rest rest rest. Viral infections can really impact the arenal system (which impacts everything else in the body), and if the adrenals don't have the necessary time and resources to fix themselves, permanent damage can occur...atleast that's what my doc said causes CFS. Without healthy adrenals, everything else in the body is just out of whack.
I myself am still looking for a good doctor here in UT. If you are willing to share any docs, please feel free to PM me.
Good luck my dear friend.
