Is doing the job on my shoulder blade I managed to fuck up by just sitting slumped on an unfamiliar office chair a bit wonky for a couple of hours. Been in pain for two days since
Back in my competitive climbing days, I had an independent pharmacy sponsor me with free TENS machine gel and Voltarol (known by another name overseas). For tendinitis and muscle sprains it worked pretty well, but like mentioned above there are stronger over the counter meds.
Hello Voltarol 👋
