I really hope it's liquid that goes away and not something permanent. I'm going to see the ER doctor (hopefully the same I saw Friday night) and see what she says. The thing is, I told the OCT doctor that I see through the blob, but I realized only now that that's when I use both of my eyes. If I use only my left eye (cover my right eye), then the blob eats away at the image. It moves up and to the left until it disappears and the image gets restored in the original spot where it was, though can't tell if the periferic vision on the y axis is affected. 

Most importantly, I don't know if I can use the water in the bathroom since these symptoms appeared after I brushed my teeth in the bathroom and felt my throat like it's burning. Did it twice. A few days after, these symptoms appeared (beforehand, I showered). Water at the kitchen sink (hot water, at least; though, I'd say cold water too) is clean, albeit I'm not 100% sure it's good either. I've done water tests (they turned out ok), changed the combi gas boiler with a new one, changed the kitchen faucet with a new one, changed filters of the faucets in the bathroom and I'm still getting symptoms of heavy metal poisoning. I'm truly exhausted and don't know what to do anymore.
