Similar time = similar spell. Only not necessarily in that order.
A volcano and a run of US tornadoes has occurred or is about to. I just had the leg cramps to go with them. I don't think it is diet caused as I am on a ketotic diet though I gave into a craving a few days back.

The tell-tale starts of with: Lassitude the first day, tighness and a bruised feeling in the muscles the next then the attack of cramps.. I also managed a touch of gout to go with it.

Anyone with an age related auto-immune disease said to be related to weather will have suffered some or all of the symptoms. The cure is to cut out all sugars and as much carbohydrates as is possible. Almost impossible in a sophisticated world as the craving will ensure that you can't keep to such a diet.

Nothing showing on:

Which make this a forecast.

Dawlish will be pleased. (You can call that a prophecy.)
