How are you doing, 59636?
Is it clearing?
A female family member showed me that she sometimes gets cracking on a fingertip. It's sore, but she didn't mention itchy. (Her diet is astonishingly bad, but I don't say anything because of her strong preferences.)
Myself, I get tiny pinhead blisters on my hands or feet. They can drive me nearly out of mind with itching. I've learned to avoid plants of the nightshade family, especially tomatoes.
I don't know what those websites have suggested, but there are two things I've found useful.
One is Grapefruit Seed Extract. Dilute with water for use on the skin, or internally, as suggested on the label.
The other is Lavender Oil. I once cut the tip of my index finger when a paring knife slipped. It was a deep cut. I clamped on it with my thumb. Then I put one drop of Young Living Essential lavender oil directly on the cut.
Immediately the pain stopped. I didn't cover the wound, and within three days there was no sign of it.
Be cautious that any essential oil you buy is of 'therapeutic quality'. Lavender oil, for example may be lavendin, from a hybrid plant that does not produce seeds, or a mixture. The slow processed kind is best, and likely more expensive, but it does the job.
Some oils, such as oregano, must be diluted with a mixing oil, because they are too strong. Never get any, diluted or not, near your eyes! That means that it's best to use cotton wool on a stick, not one's fingers, to mix or apply it.
Hope you are well on your way to recovery!
