Three times in the last 2 mths I've been getting these head colds that go away in a few hours. I get congested, groggy with a headache that lasts for a few hours then goes away. I'm not really sure what to make of it.

I do believe it started happening since I have been on the Methotrexate so it maybe from the medicine, I'm just not sure and why I am asking if anyone suffers from the same thing.
