Loving long-life heat patches at the moment, in the arsenal of attempts to get my goddamn #cyst to draw out.

These patches are based on iron's exothermic reaction with oxygen; once you deploy them, the air gets to them and heat is produced for hours at a time, while the contents basically turns to rust. Who knew?!

Shame I can't get medical attention to just tackle it surgically... massive gap in #nhs remit/capacity here, if you ask me.
