I was in a pretty serious car accident last summer (not my fault) and had some ongoing back issues as a result. Though I went the traditional western medicine route for much of my therapies, I did have cupping, dry needling and was recommended to obtain some THC/CBD salve. Its not legal in my state, but I did travel to one where it was and purchased a salve by Mary's - its the Compound, and has about a 50/50 THC/CBD blend in a shea base, but has very small amounts of menthol and camphor. It has a slight smell and minimal cooling effect - if BioFreeze is a 10 on the icy hot stink and sting scale, Mary's is a 1. It does help, absorbs quickly and is non-greasy. If you've ever tried a lidocaine patch, its about the same pain relieving effect. Definitely does NOT get you high in this topical application, though I am sure it would result in a positive THC test. Price is on the high side - The 1 oz jar was around $50 before all the taxes, but it lasts FOREVER. I use it pretty regularly and it is still at least 1/3 full. https://marysmedicinals.com/product/transdermal-compound/
I've heard very good things about Mary's Medicinals, too. They're one of the brands exploring cannabinoids beyond THC and CBD, like CBN.
