Hi, for a week now my left eye muscle, under the inner part of my eyebrow, feels as if its been strained. Looking around rapidly causes a mild dull ache to eminate from it. This ache eventually starts to give me tension headache pain behind my temples (both sides) above my left ear, as well as on top on my head on the left side. Also sometimes causes a feeling of pressure in my ears, more the left ear than the right, like I need to equalize. The most difficult thing to explain is the actual feeling in said left eye muscle. When not straining my eye on purpose, theres no real pain, and it doesnt feel exactly like pressure.. it kind of feels like something is in the eye without any scratching pain and my eye doesnt tear up. My eyes also appear perfectly normal. Lastly, maybe twice in the week, I have felt mildly dizzy for approx 5 -10 seconds - feels as if I am slightly losing my balance. I do have what was confirmed by my neurologist to be a pineal cyst, diagnosed via MRI 3 months ago but besides that no other clinical problems with my head or eyes. Neurologist confirmed it is asymptomatic as it is not applying pressure to any surrounding structures. I also have left maxillary sinusitis, which seems pretty dormant in the MRI, and I have never had any congestion or blocked nose etc because of it. Could this be some form of ptosis? Maybe it IS the sinusitis acting up?? Or is it just a strained eye muscle?
