Quote:Description:
Frequently-recurring headache attacks developing only during sleep, causing wakening and lasting for up to four hours, without characteristic associated symptoms and not attributed to other pathology.
Diagnostic criteria:
A. Recurrent headache attacks fulfilling criteria B-E
B. Developing only during sleep, and causing wakening
C. Occurring on ≥10 days per month for >3 months
D. Lasting ≥15 min and for up to 4 hr after waking
E. No cranial autonomic symptoms or restlessness
F. Not better accounted for by another ICHD-3 diagnosis.
The last point, F, is the hardest to confirm and it is why we recommend that people see a headache specialist as most GPS, even most neurologists don't have the skills or experience in this area.

Quote:Description:
Attacks of severe, strictly unilateral pain which is orbital, supraorbital, temporal or in any combination of these sites, lasting 15-180 minutes and occurring from once every other day to eight times a day. The pain is associated with ipsilateral conjunctival injection, lacrimation, nasal congestion, rhinorrhoea, forehead and facial sweating, miosis, ptosis and/or eyelid oedema, and/or with restlessness or agitation.
Diagnostic criteria:
A. At least five attacks fulfilling criteria B-D
B. Severe or very severe unilateral orbital, supraorbital and/or temporal pain lasting 15-180 min (when untreated)1
C. Either or both of the following:
1. at least one of the following symptoms or signs, ipsilateral to the headache:
a) conjunctival injection and/or lacrimation
b) nasal congestion and/or rhinorrhoea
c) eyelid oedema
d) forehead and facial sweating
e) forehead and facial flushing
f) sensation of fullness in the ear
g) miosis and/or ptosis
2. a sense of restlessness or agitation
D. Attacks have a frequency between one every other day and 8 per day for more than half of the time when the disorder is active
E. Not better accounted for by another ICHD-3 diagnosis.
Again point E is the hard one to confirm.
With the first, the main differences to CH are around the lack of restlessness and the only during sleep.
But as others have said, we can't diagnose. That needs a doctor with the appropriate skils and experience.
As Brian puts it so well, all headaches are horrible, so hopefully you get a confirmed diagnosis soon as that kicks off the right treatment for you.
Keep us updated on how you get on.
