Great posts you make! I'm still wondering about the history of the large worms, including those in the photos you posted. How do you think you became their unwilling host? I wonder how many of us are infested with such large invaders?
Anyhow, if you need a good balm, try picking some plantain leaves(Plantago sp.- either common species will do), and smashing them up with coconut oil or shea butter, etc. Include Heal All (prunella vulgaris) if you can find that, which you probably can.
