Last night I suffered a bout of debilitating panas-dingin; the third time in four years. The good news is that it lasted less than three hours compared to the first time of almost 3 days and the second of under a day. The debilitating symptoms are extreme cold shivers such as to make movement impossibly painful. No amount of warm fluffy duvets have any positive effect. I originally thought that it was recurrent malaria with the bodies immune system becoming increasingly effective, but "no" my friends tell me. Doctor tell us that "panas-dingin" is well "panas-dingin", a websearch doesn't help and GoogooTX offers "chills". Hmmm. It's pretty common out here in the tropics and I'm sure others have succumed. But what is it exactly?
