I'm having some trouble with upper back pain near my neck and shoulder, and it's really starting to bug me. Sometimes I even get this mild breathing issue, but its kind of on and off. When I sneeze, there's this weird foul smell thats really bothering me. I've had a spirometry test done and it came out normal, so there's that. I know I'm low on vitamin D, so I'm taking supplements for that. I've also been feeling joint pain in my hands from time to time. Any ideas on how to deal with this upper back pain? And do you think all these symptoms are connected somehow?
