Has anyone here been successful at eliminating parasites in the head and face?

I ask this because if I can't get rid of mine soon then I will become as crazy as everyone I know already thinks I am. I've decided that I am going to take meds as I'm doubtful as to how effectively the herbs would reach my head and face. Although if anyone here has been able to draw them out of parts of the face (sinuses, temples, eyes) by using herbs then please let me know.

A few weeks a go I visited an Opthalmologist to see how my eyes were because of the foreign body sensation I'd been having in/around them and more twitching for a couple of weeks. I can sometimes feel crawling over my upper lid when I shut my eyes too. He ran a standard eye exam, vision all ok, I did report to him that I have floaters and my vision is somewhat speckled/visual snow in the background of it. He took a photo of the back of my eye and my retina which gives you an image of the eye from the inside and didn't find anything in there. He did however tell me that the reason I have the foreign body feeling in my eyes is because of a problem with the muscles and that my lower lids were turning slightly inwards. It could potentially become Entropion which only people in their 60s
usually get and I'd need an operation to correct this.

What I want to know is, can parasites cause this? I do look at screens a lot but I don't think I was getting this eye problem until I'd taken my first parasite medication. I do have low vitamin D levels as well though, could it just be this? I've been washing my face with Sea Salt , used some tee trea oil on it before, a Bentonite clay mask and I've bought some bloodroot to target my sinuses after seeing Glaxony's post. Can anyone suggest to me how to use this btw? I'm thinking to dab some on cotton wool and apply topically or inhale it. I've got Dr Christopher's eyebright forumla too but don't have the distilled water to use with it, I don't know how much this matters. Wish that I'd gotten the one by Dr Schulze as his one has more positive reviews. I've been juicing carrots with orange juice as well.

I could just really do with more help cos I feel so fatigued from how my head and eyes are constantly. I can't seem to get on with my day as I would cos of it, without needing to nap a lot. My head and scalp feel tender or achey a lot of the time as well and some short sharp pains, especially the back and left side. A couple of other questions that I have, can parasite meds cause further scattering? and I've had a CT scan of my head, they found nothing sinister, does this rule out Toxoplasmosis?
