Yes, I've struggled with this off and on but not sure whether related.

Yes. Mine run especially when I lay down or do any physical exertion. Mentioned it to the doctor and he looked at me like I had 2 heads.

Mine go from being running like I'm crying to bone dry and itchy. I am not sure how much is my allergies though.

thats what Im wondering if its just allergies

Yes, was told it was just allergies.

Since being on diamox I have actually noticed the opposite. My eyes are super dry. I mentioned this when I was at my neuro-ophthalmologist office because I saw they had sample bottles of eye drops, and he let me take a bunch lol!

Allergies can cause wet eyes. So can some kinds of headaches, like a migraine. don't know about IH.

Sea is right, most wet eyes can be from allergies.
Cluster migraine , one of its symptoms is a watering eye, but! Only in one eye.
Diomax, that devil drug, acts as a diuretic , drawing all fluid from your body not just the csf.
My finger nails flatted when I was taking it!
You must always keep your fluid uptake high when you are taking Diomax, even tho it can mean spending a lot of time in the rest room!

Most of us will have dry eye, I have found out. Now why I don't know but we should all be using drops.
I had sore, itchy eyes and part of the problem was dry eye. Since I started the drops it has helped so much.
I started with the water and have now moved to the gel which I find works better for me,
This is one of those win win times. The drops are cheap, they are easy to put in,and it helps.
So off you go and get some relief! ( fingers crossed!) Cath.
