My dad is 77. He had some flu or sickness or possibly mild heat stroke a few years back. We took him to the hospital to be checked as he has diabetes and a prior stroke in 1994.
He was not feeling well and seemed weak but was not in terrible shape. He spent some time in the hospital and they never determined what if anything was wrong. they finally decided either an infection or a minor stroke.
He later had confusion which still comes and goes.
The one thing he came out of this with that has not ceased is a constant drip from his nose. Not snot. Clear water thin liquid. It drives him nuts and he has to have a hanky right there all the time. he can hardly eat as the drip gets faster
when he is eating.
I wish I could solve this for him so at least he would have one less problem.
also he can't take decongestant/benydrl type medicine
