^ It's important to have your eyes checked if you have a sudden increase in floaters, but also check that you're not just being more aware of the ones you already had. I tend to find mine more noticeable at certain times of the year when there's more direct sunlight, and also at times of the day when the sun is fairly low in the sky. Bright light makes them more noticeable, and once you focus on them your brain stops filtering them out for a while. Your optometrist/ophthalmist should check your retina for signs of tearing. They'll give you eyedrops to dilate your pupil--if they didn't then they probably haven't done that part of the examination.
Pains in and around the eye can be caused by the surrounding muscles squeezing the eyeball to optimise the curvature of the lens; that's your body's attempt to compensate for deteriorating eyesight. You might not notice your eyesight worsening at first, but there's greater strain placed on your eye if you don't wear corrective lenses. If you ever hear your eye creaking when you move it, that's all the more likely the cause. Your optometrist/ophthalmist should check the pressure in your eye (also testing for glaucoma) either with a device that blows a puff of air into your eye or lightly taps on the surface of it. The latter one freaked me out the first time I had it done, and made me blink a lot, but it doesn't really hurt.
I had some 'fun' with my eyes last year when I suddenly developed a blind spot. Initially they thought it was a cotton wool spot, but those are supposed to resolve after a couple of months. After several months of tests and escalation to a consultant the verdict was basically a shrug. His exact words were, "I can't treat what I can't see" (even though it showed up on the photos his team had taken), and then he discharged me. So now I'm left with an unidentified permanent blind spot, and no idea of what caused it or if I'll get another one at some point. The wonders of 21st Century medical science.
Other 'fun' stuff recently: chronic tinnitus, waiting on the results of an MRI to see if I have a tumour in my head, anxiety attacks, my workplace is being relocated meaning I'll lose an extra hour out of my day to driving time, and that'll make it even more difficult to work on my master's dissertation in my free time (which was already driving me up the wall).
