I need answers

Been dealing with swelling around my left eye and cheek swelling for over a year now and have saw eye Dr after eye Dr along with an ent and made many hospital visits and still no answers to what is going on. It’s just on the left side of my face . My nasal on the left is usually congested and I feel just wierd on the left side . My eye in the corner towards the nose always feels like something is there but the Dr says )I don’t see nothing wrong with it ) Im on doxycycline currently been on amoxicillin for months (just Incase my teeth decide they wanna get infected cause they are bad ) they are trying to say it’s a headache disorder but I get the headaches from my nasal being dry and my eye . Any advice would be great cause I’m not sure what to do at this point
