Exercise and Last Night

The toughest part of having fibro and autoimmune diseases, is that others have no idea how you can be feeling.  Yesterday after work (well started after lunch at work), I had a big flare up.  I had walked about 2 1/2 miles at lunch time, and my body didn't seem to like this at all.  I am used to walking, but hadn't walked in about 2 weeks, so probably over did it.
Anyway, I had a flare up where it felt like my body was igniting the ends of all my nerves throughout my entire body.  This is so hard to describe, even to myself. And, it's very scarey too.  When I flare, it affects me physically and mentally.  I just don't understand how my body can decide to "turn on" the nerves like that. Eventually the flare up subsided, with a little help from some Tramadol, which helped to calm me and dull the pain. My arms and legs hurt from the tingling and numbness that spreads up.  God, I hate this.
I'm back at my desk at work this morning.  Sometimes, I don't know how I can do it but here I am... my family, my co-workers and everyone else thinking I'm all just fine and dandy.  It's a bad day. Somtimes I just want to scream.
