Is it possible to have a small Cerebrospinal Fluid (CSF) Leak, after a Hemorrhagic stroke 1/ At all. and 2/ still after 3+ years?

I had a stroke (haemorrhagic ) 3.5 (2007) years ago, I thought all would be good, it would be OK in the end. It wasn't and it's not. I have had the symptoms of a cold now for 3.5 years, I thought it was from the medications that I was on so I mentioned it a couple of times to my doctor but also thought I'd get used to the meds. When I had the stroke, I went deaf in my right ear and totally numb on the right side from top of head to foot, I was told I shouldn't be able to walk, but I could, and was quite stable. In spite of the numbness I could also use my hand although it is very frustrating at times i do have a certain amount of feeling has returned, but it seems/feels like1 layer out of several has lost what it needs. Any how, getting back to my "cold" and ear, I can "feel" the entire length of my ear canal... It seems hollow? hot? the hearing has returned (as much as was there pre stroke anyhow, was never that good, I now have hearing aids but rarely wear my RH one as it is just too annoying on that side.) To the "cold", my right nostril "drips" to varying degrees and is not consistent in it's flow, if I have my head down, "thinking, toilet, bending over .etc I can feel the fluid run down the upper side of my nostril, I blow my nose... I'm talking 1-2 boxes of facial tissues per week... per week for the last 3.5 years. Connection: Nostril - ear canal. Mark Hunter.
