Ouch my feet!

I have this problem with my feet. It stinks! Hehe... this problem of mine, I don't know how to resolve it permanently. My feet is prone to blisters and also fungal and bacterial infection. This infection was the worst in April where it had infected my leg and groin muscle and as a result I could not walk properly. It happened again this week. Decided to see a specialist at National Skin Centre. Didn't think that the total cost of consultation and medication would exceed $100. But alas, it went up to around $160!. Checked that one of my medication costs ard $63 for a box! Now I know why they say medical costs in SG is rising and only the well-off can get good medication. As of now, I really need to take care of my feet. Wouldn't want such thing to happen again.
