From what ur describing with ur hands brother from experience is most likely cervical related. Being ur healthy there gunna make u do thing like physical therapy, then come the injections which is pointless they will do things like nerve blocks and steroid/anti inflammatory agents. You'll be out of pain for a week or two at most shots is there new way to whack ur insurance with a nice hefty bill... Clearly somewhere u have a pinched nerve depending on how that nerve is pinched like say a herniated disc sometimes the disc will after time and after the initial inflammation passes it can slide back into place, this doesn't happen all the time. Good thing is if they can pinpoint the nerve and the area u might be able to do a minimal invasive surgery.... If u really messed up the disc they can actually go in remove the bad disc and put in this new disc it was made by the Germans acts exactly like a disc nice a firm but has some gel like five to it and they lock it into place with a cpl screw 2 to 4. My buddy who is a pro surfer had it done he chases big waves for a living and took a bad whippit right in the wrong spot and whinded up crushing his disc actually tore it in a cpl places. They went in and did that surgery and he followed the physical therapy and he is 100 percent better. He couldn't even paddle or surf after the injury couldn't pick his head up off the board without serve pain.... Thankfully being he is a pro he had access to really good doctor and surgeons. If ur on the east coast and consider surgery look into the surgery center up in NYC for back surgery top of the line surgeons. Hopefully with some predisione and some other anti inflammatory drugs it'll calm and relax things enough for them to heal on there own... If u have a belt squat machine I would use that over doing or putting anything on ur back or neck. Really I should be resting... The cervical is scary cause where there at but it's one of the easier places to do back surgery, lumbar can turn into a nightmeare.... I would also look into bpc147 and tb500 that may help with the healing along with any inflammation... A small dose of gh 1 to 1.5iu can help with bone health. Just a few things worth looking into. The peptides though can absolutely help and do wonder expecially bpc157.... Best of luck brother hope everything comes back and u feel better
