Re: CDB oil, I use a topical product called Deep Relief from cleancoconut.com. It has CBD hemp oil, no THC, lavender oil and coconut oil. It is not sticky and is the only topical that has helped me with burning nerve pain at the skin level (armpit & upper arm) from a nerve being nicked during surgery. If you suffer from this type of pain, it is definitely worth a try. I have also used it on occasion to soothe lower back pain. Good luck.
