Is it normal for your eyelid to droop?

I was about to post a similar question.

I know about Bell's Palsy. But this is not as bad as Bell's Palsy. When I'm really not feeling good, my left eye (not eyelid) gets a bit droopy, when I smile, that same side of my mouth doesn't go all way like the other side of my mouth, when I talk, my mouth doesn't move symmetrical.
It's not that bad, but I see it when I talk on Skype with friends, or when I look at the mirror.

Can one side of your face become 'lazier' than the other side, without having the severe symptoms that you can see on someone with Bell's Palsy?

I'm sorry John, I don't want to hijack your thread at all

Do both of your eyes feel irritated, or just one? Is your nose dripping/stuffed, on that same side? Just wondering because I have frequent cluster headaches: they are located on one side of my head, my eyelid gets droopy, my eye feels very irritated and it feels like an icepick is stabbing that eye.
Just an idea?

Neurological symptoms and signs including:

Headaches.
Neuralgia/neuropathic pain, ie pain which may have a pricking/stinging quality, with excessive sensitivity to light touch or pressure.
Cranial nerve disorders: facial palsy (sometimes involving both sides of the face), double vision, drooping eyelid (ptosis), numbness pain and tingling of the face, hearing loss, dizziness and tinnitus.
Seizures.
Autonomic dysfunction – problems in regulation of pulse and blood pressure eg POTS (postural orthostatic tachycardia syndrome).
States that mimic other defined neurological disorders such as Parkinson’s disease, MS, Bell’s palsy, stroke, ALS, Motor Neurone Disease.
In children, indications of neurological involvement include behaviour changes, learning difficulties and headaches.

I noticed one of my eyelids drooping (very noticeable) and on the same side my mouth doesn't move like the other side. My first LLMD appt I was told this comes with having Lyme. He said it is a form of Bell's Palsy. I have severe pain behind both eyes at times. Sometimes it's so bad it feels like someone is in there trying to push them out. It can also feel like my eyes are filled with sand. My eyes are very bloodshot most of the time and I see flashes of bright lights from time to time. I've also had black floaters. All this I'm told is symptoms of having Lyme.

Sorry you have this issue.

This happened for about 2 weeks to me about a month ago as well while on the rifampin. This is infection of your cranial nerves that goto the face. For me it was also the left eye! But it was not drooping, more like it felt mild weakness. I don't have this symptom anymore though. I also felt like I had an infection inside of the eye, like the eye was kind of going numb. Again it's gone now though.
