Prevention is better than cure they say. the human body is not an engine that can shut down and be fixed later, some people use their health like it's a public transport and this shouldn't be. About 2 month ago I noticed that I was having a red eye, and it was itching me as well, at first I got an eye drop, after using it for few days it got better and then came back again, it did that over and over till I decided to visit an optician some days to Christmas. I ended up paying almost all I had for the treatment, but I feel better now, who knows what would have happened if I decided to spend the money on other things for Christmas.
One better thing is that once health is not treated on time and it starts to ask up real bad, nothing else will feel the same way, even money will have no use by then.
