Welcome to HW! I'm sorry to hear about all your pain & especially that you still remain undiagnosed. I know how hard that is!! I am in the same boat...been dealing with this for 2 1/2 yrs & still nothing (and yet my symptoms keep progressing). Basically, I had a traumatic injury to my eye several years ago & came close to losing the eye & now I am stuck with severe chronic pain (which we have yet to be able to control in any way) & diminishing vision & function of the eye. I just saw a new doc today, a rheumatologist, but it was a waste of time. Fortunately, I expected it to be so ahead of time. One of my docs thought of some abstract condition (although 90% of the symptoms didn't fit with my case from the beginning) & so sent me there. As I expected the doc didn't have much to say. He thinks it might be RSD/CRPS (which has been mentioned before, so, nothing new), but that is out of his territory. He did seem genuinely upset, though, that he couldn't help. Even though I expected this outcome, it was nonetheless disappointing. I'm just scared that no one is going to figure this thing out & that it is going to keep getting worse (as it is already doing) & I'm going to end up losing all my vision in this eye (not that it hasn't already been irreparably damaged) AND be stuck with the severe chronic pain that has plagued me fore 2 1/2 yrs.
Not having a diagnosis is scary & frustrating, and disappointing, so I truly hope that someone comes up with something for you soon. Chutz's idea of fibro & seeing a rheumatologist sounds like a good one to me. Can't hurt anyway.
As for your "herd," wow! They must be hard to take care of with all your pain! But I am quite jealous! I'm on the road to becoming a vet & I want to work primarily with large animals. I'd love to have horses, goats, and a couple cows one day (alpacas are great too)! I just need to figure out this whole CP thing, so that I can make it through the rest of my schooling (one more year of undergrad & then hopefully vet school).
Oh - another thing. Have you ever tried any alternative therapies? If you are willing to try & can afford it, you might think about trying something like acupuncture, cranial-sacral therapy, or seeing an osteopath who practices cranial-sacral manipulations. Sometimes, when conventional medicine can't help us, alternative therapies can do wonders!
