How long does methotrexate take to work?

I'm supposed to start taking this. I'm scared. Secondly I have infection and they still want me to start. Saying that this is better because I'm having too many infections so I need to start it. Um, won't this make infections worse? I have severe gi issues. I mean I can't hardly leave the house its so bad. My intestines cramp. My stomach is tender...so I don't see how this is going to work. I'm so sick with my gi issues I'm at the end of my rope. My other pain is scondary...except my lymphedema and my nerve damage to my back. But this isn't going to help those things. I need to get my gi stable. What do yall think? I'm really nervous...

I'm on 2 months of the mtx pills and I'm feeling an improvement

I got sick on this med it gave me fever and I was so sick I stopped taking it.
