@kjconrad Tingling and neck pain can be a spine problem or a nerve entrapment issue like thoracic outlet syndrome which can be caused by an injury to the neck or chest. TOS can affect breathing because it affects some of the muscles surrounding the rib cage. You might want to start with a neurologist who can figure out where the tingling is coming from. TOS is aggravated by a forward arm position and rounded shoulders and even forward neck positions, and you might be doing that riding the spin bike. Physical therapy and myofascial release can help TOS and correct posture is really importrant. I have TOS and I also had cervical spine surgery. If you suspect a spine issue at all, don't let anyone manipulate your vertebrae because it can injure you if there is an underlying problem. Here is some information about TOS and our discussion on MFR therapy with lots of links and information. You can find an MFR therapist at https://myofascialrelease.com/find-a-therapist/ , but you will need a doctor to determine if you have any spine instability before you let a therapist work on your neck. Your therapist should ask for this so they understand what they are working with. MFR is gentle stretching and not chiropractic manipulation. If the tight tissues are released, the muscles and bones can go back in line where they belong.
