Diagnosis???

I am really not sure what I have and neither is my doctor. I'll start from the beginning. It all started when a swollen lymph node popped up in my neck over four years ago. That gland to this day is unchanged and more of a nuisance than anything else. Its not painful but I can always feel it there. My doctor said it felt perfectly healthy and did a CT scan of it which came back normal. All blood test perfectly normal. Then I started to get this pressure around my right ear, which is the side that the lymph node is swollen on. I still have that pressure in my head. it moves from the top of my ear to right behind the ear. Once again its not painful but more of a nuisance. My primary doctor sent me to an ENT who did a CT scan of my sinuses which came back normal. The ENT thinks I have chronic allegies.

Just recently, about 6 months ago I started getting these weird blobs in my vision. I know what floaters are but these seem different. I now have all of these random symptoms and no clue what is going on. I have no recollection of being bitten by a tick but who knows....some of the posts on here sound like exactly what I am feeling. Also a weird brain fog as of lately. I'm usually a very sharp individual but lately I just feel slow. I've got a masters degree in finance and work with numbers all day so it makes things difficult. Any information is appreciated.

Once again my symptoms

-Swollen lymph node (right neck)
-Floaters? perfect eye sight but random blobs
-Pressure around right ear - my biggest annoyance - if i apply any pressure to it such as wear a ball cap or sunglasses, it goes away
-Brain fog
