I truly feel for you and your daughter. So much so that this is the first time I have ever posted or responded to a post.
As a child I had severe insomnia accompanied by pain. I was told it was “growing pains” and would pass. My academic struggles were noted. However, I was never referred to any specialist as my grades were “good”.
Thirty plus years ago I was diagnosed with Fibromyalgia by the Mayo Clinic; those restless nights with non-Restorative sleep, never ending pain and daytime cognitive dysfunction did not pass.
Recently I was diagnosed with ADHA. I just this week started treatment/therapy with an Adult ADHA specialist. For the first time in a long time I am hopeful.
A relatively recent (small) study found 40+% of individuals with fibromyalgia also tested positive for ADHA and suggested that individuals who test positive for Fibromyalgia should also be tested for ADHA.
Should you decide to have your daughter tested, I beg you to find a competent specialist. Far too many practitioners are ill informed.
I am struggling today with pain, fatigue and “Fibro-fog”/ADHA(?) so I do hope my response makes sense.
I have included some links below that I hope help you understand my response. Hopefully filling any voids or incongruences.
I wish you and your daughter all the best,
