Some invisible illnesses follow a pattern, or so it is theorized. I have tried to ruminate about these theories. Fibromyalgia has certain nuances that give way to these theories. It seems that fibromyalgia will get worse with the weather, depending on what the barometric pressure is doing. As do migraines.
Interstitial cystitis flare-ups can follow women’s menstrual cycles. Of course this is not to say that is all that causes the flare-ups, there are many, many ways to cause a flare-up of IC.
There are too many invisible illnesses to give each a comment on this short post. I really just wanted to get those three daily prompt words taken care of. But you learned something anyway! 🙂
