Hi, Deb, and welcome! I also have Crohn's disease but it is under control so I'm not having to take medications for it. But, when the fibro hit me, it started in my toes and worked it's way up my body and then hit my elbows and hands...all in 45 minutes while I was watching TV. My elbows were the worst. It was like I banged my elbow hard and I felt "electrical shocks" running down my arms but it never stopped for over two weeks! So, yes, you can have the "joint" aches and pains. The reason I put the word joint in quotes is because it's actually the muscles, tendons, and ligaments that you are feeling...not actual joint pain that you have with like rheumatoid arthritis. Fibro doesn't affect the joints. It just feels like that. So, that is good news for we fibro sufferers.
We also have what we call fibro fog...at least most of us do. When it started with me, I was really frightened because I thought I was coming down with Alzheimer's! But, once I found out that fibro caused that, too, I relaxed about it. A good sense of humor does help with that problem.
So, you might want to talk to your doctor about your possibly having fibromyalgia. If they are not sure, they will probably refer you to a doctor that can truly diagnose you. Let us know what you find out because we really do care!
