Unusual Blood Test?

I just got a call from my Rheumy that my last blood test after starting methotrexate has come back abnormal. This is only my 3rd one. I also just has a physical at work last week. My urinalisis tested with "trace" amounts of white blood cells, indicating a possible infection. What the heck??? I was allergic to Plaquenil and got a rash all over, within a month of starting to take it. And now,...I've been taking the Methotrexate for about 3.5 months now, and am starting to get test results indicating that my body is getting "annoyed" with it?!?!?!?!? I feel like I just get myself up and on my two feet, and then,...Wham,...another "sucker punch"!!! I was afraid the Meth. was not agreeing with me. I'm have nausea all the time, and I just don't feel like I've got a lot of helpfulness from the drug.
