Nope, it doesn't sound ridiculous that you've been staring at the MTX prescription for 2 weeks -- I couldn't bring myself to do it for 6 months. When I finally did get it filled, I was glad I did. Did he give you a folic acid prescription as well? You'll need to take that as well, when you're ready. Your doctor is being pro-active by prescribing the MTX, but he could've said it just a bit better, in my opinion.
Have you had any xrays of your hands, ankles, hips & pelvis? If so, what does the doctor say about that? If not, you really need to have some done -- to see what's going on. If I had to rely solely on blood tests, I would be bedridden. I am seronegative for the RF, my sed rates and the like are always in the normal range (even in the midst of my worst flares) and except for redness on my knuckles, I just don't look like there's anything wrong on the outside. Thank heavens for xrays - they tell the entire story of my RA & AS.
Ya know, we all react to med's differently. MTX is one of those drugs that doesn't always give the same side effects to us. I had nausea (felt like morning sickness) and I had hair loss. It didn't make me any more fatigued than I already was and I didn't get any mouth sores. The pills did bother my stomach some though. To help with the nausea, hair loss and stomach issues, we upped my folic acid to 2 mgs (from 1) and switched me to injections. Big difference and it's been just about 3 years now. My monthly liver tests come back fine and I do my injections weekly (except for the past 3 weeks - long story, not MTX related). It made a big difference in my RA - we added it as a supplement to Enbrel when the Enbrel stopped being as effective as it should have been.
Since MTX is a weekly drug - I do my injection on Friday night before bed - if I have any side effects, I'm asleep! Try that - take it before bed and see what happens. It's only a suggestion, but it may help. If you haven't yet, try a heating pad for your hips and pelvis. It helps me when I need it. I can't do pain meds, but I do take ibuprofen (prescription strength) when I need it.
Sorry for the long post - I just wanted to try and allay some of your fears. Hope this helps some.
