Thanks for letting us know the symptoms you are wondering about most and whether they are due to the arachnoid cyst or the traumatic brain injury, @neet. Hoping members here like @cathyinin @qball2019 @em87 @gloriajean @jseibert @kyoto can add some insights from their experiences with arachnoid cyst to see if these symptoms — the loss of smell, tinnitus and weird feeling in head when climbing steps or looking upwards — might be similar to what they have gone through.

Did your doctor have any thoughts on what your symptoms may have arisen from @neet? Have you received any treatment for them yet?

I am 48 yrs old woman from Ontario Canada just diagnosed with arachnoid cyst on brain, I do not know the exact dimensions...well, picture is worth a thousand words. I had MS like symptoms (vertigo,headaches, diziness, nausea, double vision, memory loss), which triggered the need for MRI. I was referred to a Neurosurgeon who recommended another specialized MRI plus procedure with camera to figure out best COA for surgery so to not affect language. I started having tinnitus approx 2 weeks ago left ear, right ear two days later. I was told most likely due to virus...the answer to anything and everything these days! I was given nasal steroids for the tinnitus which doesn't help thus far and got nosebleed today. For as long as I can remember I felt like my sense of smell was off which I assumed was because of multiple sinus infections, rhinitis, allergies or deviated septum. I am waiting for a date for everything ,this is two weeks after the initial appointment and I was told surgery in a month or two. Waiting game now...
