Multiple Medical Conditions

I am sure many who have Glaucoma have other medical considions. I am wondering how Glaucoma interacts with other conditions.Some may be more obvious such as those that interrupt blood flow to the optic nerve. I am curious though, especially from the self monitors, if Pain can raise the IOP. Today I am not walking due to pain. This is due to arthritis flair and very much pain. I had my heart checked and my pulse isnt raised. Has anyone found if pain levels raise IOP at all?
