New member here, stumbled across this site. Have been having some major issues since July of last year. I'm not sure where to start without having long explanations. I can tell you that I had an MRI on my brain back in August as well as a CT scan which were perfectly normal. There was only an incidental finding which said:

"In the cavernous sinus on the left there is a partially fatty lesion with some surrounding cystic component which demonstrates a punctate central calcification. This may represent a small dermoid. It is fairly well defined. Six month follow up MRI with attention to the left cavernous sinus is recommended. Obtaining a fat-suppressed image is also recommended. If the patient has clinical symptoms shorter-term followup is recommended. This would include cranial neuropathies of the III, IV and VIth nerves. I do not believe that this impinges upon nerve V in Meckel's Cave directly"

I've asked an ENT, Doctor and neurologist about it and they said it was normal. My current symptoms are as follows (symptoms I have not had for 36 years of my life):

-Suddenly afraid of heights

-Feel like I'm going to fall backwards going UP escalators

-In movie theaters or stadiums, I can't sit ANYWHERE. Even in some certain chairs. I feel like I'm going to panic and like I'm going to black and fall over (in bar chairs too). The last time I went to a stadium, I left because I felt like something was going to push me forward from behind (we were very high in normal seats I have always been in for the past 5 years for every week). I have not been back to a large venue like this since.

-Loss of weight (all tests for cancers that I have done, have been negative). Weight loss was mainly in legs, which always used to be big and muscular.

-Slight tinnitus in right ear (very faint, only heard when it's quiet)

Some of my past diagnosis and issues I've had the past 6-7 months when this all started:
-A bloody nose when this started with a feeling like I was going to pass out
-Had a neck/upper back issue which I went to PT for
-Had allergy testing done
-Had to get a crown put on a tooth (dental work)
-Issues started to happen after all of this, main symptom started during PT
-Doctor's found Hep B in me but assured me it was not causing this symptom and it was a mild case I had
-Neurologist said it was a Vestibular dysfunction
-ENT said it was an inner ear issue and later told me it was Meniere's because of the ringing in ear. Ringing in right ear started 2-3 months after the initial symptoms started so I doubt it was this (plus, the room has never spun on me so there was no vertigo)
-Low Vitamin D and Low testosterone

I'm unsure what to do at this point. The symptom is still there and VERY debilitating on life in general and things I enjoyed, I can't do now. Would the issue in my sinus with the lesion cause something like this? Should I get it removed? I'm very confused by what is causing this and nobody can give me a real answer.
