Flare up? or disease progression?

Being that I have had RA for less than a year, I am still learning what the heck my body is doing. I had been doing quite well on Enbrel and Methotrexate. My Doc suggested Cellebrex and to raise my MTX a bit, but after reading the side effects I just didnt feel it was the best option for me. But lately I am wondering if perhaps I should start increase my MTX and start the cellebrex. I find my hands are stiff, my left pinky hurts most the time, every single joint cracks when I walk and I feel a little more stiff than usual. Now, how do I know what this is? Is it a flare up? or is my RA progressing? Is it the weather? Stress from life and school? I dont see my Doc till December, any feedback would be greatly appreciated. :)
