Does too much caffiene increase arthritis aches?

Im a 52 year old female and I can tell you that caffeine will definitely flare up your arthritis. I found this out by acident and know its true.
I had my arthritis under control and then took up drinking coffe at work because a new co-worker always made a fresh pot everday and it smelled so good I couldnt resister.
I had coffe and noticed within a few hours the pain would
start=mostly aching in my feet and back. I guit drinking it for a few days to retest my suspicion & was right.
I also looked on the internet and found a site that mentioned coffee and fried foods can irritate it.
There is some really good information about it out there.
if you just look.
Good luck
