Hi. I'm online and happy to answer your question today.
Ocular pain is not common in fibromyalgia.
sometimes i have pain behind the eyes on waking after previously working the night before from 4 to 9 and not eating dinner a my normal time just having something when I arrive home at about 10 I then go to sleep at about 12. The previous day I would have had lunch at 12 noon and not had much to drink could this be dehydration.
