Safety of lifting with intracranial hypertension

I was diagnosed with idiopathic intracranial hypertension. Given that Valsalva maneuver increases intracranial pressure, would it be safe for me to lift?

I currently don’t have any symptoms except small headaches or brainfog but I have never experienced the symptoms while lifting. My brain already has some changes (fluid around eye nerves, partial empty sella) due to IIH.

Unfortunately I am not aware of any evidence here, and am not going to be comfortable providing advice on this particular topic. Sorry.
