About 12-18 months ago, I started having generalized but pretty severe (often a 7/8 out of 10) stomach pain. Not reflux (I know that pain). Not gas (I know that too). Not down in (what's left of) my bowels. The pain was located in a sort of arc around my rib cage. Nothing helped.
A colorectal surgeon friend said the pain could very well be "residual" pain from scar tissue left over after colectomy. She said there is probably nothing to do, and I just had to live with it. F that.
On advice from a friend dealing with Rheum Arthritis, I tried 30:1 CBD:THC tincture. 1/2 ml, 2x per day (morning and afternoon). It actually worked!
I have now tried multiple branded CBD tinctures. Some work better than others. THC is actually the key. You need a trace amount of THC to trigger/activate the CBD (this I've learned from experience and from much reading and discussion). SO, the CBD tincture must be derived from Cannabis plant (which has THC) and not Hemp plant (which has none).
The 30 parts CBD to 1 part THC ratio is key for me. The THC is so minimal you do not feel high at all. You may not need 30:1. I've seen tinctures with 4:1, 5:1, 15:1, 20:1. As ratios go down, however, I've noticed that the 'highness" goes up. 1:1, for example, is basically smoking a joint.
The tincture is made of "MCT" oil, a highly soluble form of coconut oil.
Hope this helps. J
