Fibromyalgia Support Group
You're not alone in your pain. Fibromyalgia is a condition that can be difficult to diagnose and manage. If you're trying to cope with pain throughout your body, sleep problems, general fatigue, or other common fibromyalgia symptoms, you're in the right place. The community is here for you to talk about therapies and share your challenges.
The one thing I discovered recently is that apparently most of my nail problem is because my nails have become hypersensitive to household chemicals I have been using for decades- like Windex and cleanser.
I am not fond of rubber gloves but have gotten better about wearing them and my nails dramatically improve when ever I stick with this.
I have also reduced my use of cleaning products (e.g. just using a wet paper towel to wipe up a coffee spot) and recently hired a housekeeping company so I can just stay away from those chemicals.
You might look at what your nails get exposed to, to see if maybe they have developed a sensitivity. Many people as they age get vertical lines/ridges in their nails, but it's the splitting that is a pain.
Good luck with this.
