Horrible eye sensations for months

Hi everyone. I've been getting these really horrible eye strain feelings and twitches. I've been to the doctor and been told to go to the optician so I did, and turned out my eyes are fine. It's like an invoulentary spasm that causes me to do hard blinks, force my eyes to look upwards and to the left or right, get pain around the eyes and I tend to have constant dark rings/bags. This can lead to headaches either on the left side of my head or in the center of my forehead. Where I have a history of anxiety I can't tell if it's anxiety that's causing this or if this eye twitch is making me worry overly about it. It's been happening for months and is seriously affecting me. People ask if I've been punched in the face because my eyes tend to look dark (more so my left than my right). My doctors don't seem to want to go any further with it and don't give me any sort of explanation but just tell me to use eye drops which I've been doing and had no difference. Like I said being an anxiety sufferer I cant help but think I've got some sort of brain tumor or something, especially as most of the time it affects my left eye and head more than the right. (although I know it's very unlikely). I get a decent amount of sleep no less than anyone else my age (23) and don't do anything out of the ordinary. Does anyone have any sort of idea what could be going on?, my half brother also has the same sort of twitch although not on the same scale as mine. So I don't know if it could be something in the family. I'd really appreciate any sort of replies or comments so if anyone has anything to say please don't refrain from messaging me or replying to this thread. Thanks alot guys.

my sister gets very bad eye twitching when shes very stressed and i get it sometimes too.

easily attributable to anxiety. it cause contractions of involuntary muscles, muscles we dont normal have direct control over. normally head, kneck chest or stomach. if certain muscles are contracting, can block lymphatic system, where fluids/chemicals within tissue cannot drain away. bags and dark areas around eyes can be symptoms, for example people who have not had enough sleep. easily attributable to anxiety.

I just find it so weird how I never feel anxious or anything and seem to have this constant eye twitch. It’s not like a muscle spasm it’s more like I know I want to move my eyes like that and I can stop it if I really try hard, but I just end up doing it to relieve that feeling of needing to do it.
I did used to have the same sort of thing where I felt like I needed to click my neck or move it.
Just seems weird how I never feel anxious whilst it’s happening for at least 6 hours of the day or so.

Thanks for getting back to me by the way

Better that you consult an opthalmologist than an optician.
