Hello Smalltowngirl and welcome! Yes, I have a real problem with balance and falling, as well as dropping things repetitively. All three seem to be cyclical for me. But I can't tell you how many times I've fallen down stairs since I got fibro, even a few easy steps down. And yes, it's always when I am going downstairs!!!
My recommendation, and you probably won't like it- is to get and use a cane. There, I got out the horror if the suggestion! But seriously, yes, a cane has prevented me from taking falls many, many times. And you can find some really cool ones on eBay if you dig aound a bit. I have a basketful of them in all different colors and designs. I use them like an accessory, which takes away the stigma of using one, and have gotten some nice comments on them.
Your medicines could also be making you tipsy. I know when I first got on Lyrica I felt like the entire world was on a tilt for the first month or so. I think your absolutely best plan is to address this again with your physician to make sure it's not your meds.
Good luck with this and I'm sorry that you have fibro at such an early age.
Hugs to you,
