Brother, 10 year recreation smoker and now+ 10 year dependent THC user here.. First, don't smoke if you do. Edibles are good for night, but slower. A pure THC oil vape pen has the best dose control.. least carcinogen (no combustion, smoke).
And new US vaping deaths are mostly tainted black market tobacco e-liquids, not medical grade THC/CBD oils.
Second, it does elevate heart rate a bit for the first 30mim, avoid sativa if you want to chill and recover choose indica and CBD. Sativa are more mental, creative high, but won't let you relax... Indica are more a body high, hence the term "couch locked". Indica will help you nap and CBD blend will act as natural NSAID and additional chill.
Man, hope you take it easy get well first!
Also pretty experienced in tramadol and diclofenac. An oral synthetic opoid with a topical NSAID. That should work well.
EDIT - I am trying to quit THC myself like
