What causes tingling in the neck and left jaw with COPD?

Hi toolate32 and thanks for posting your inquiry. While we cannot provide medical advice or diagnostics over the internet (for your own safety), your concern certainly warrants a comment. The symptoms you describe may not be related to COPD - it's difficult to determine that here. However, if the symptoms (neck tingling and left jaw pain) persist or worsen even, you may want to check in with your physician to determine what is causing these issues.
Please do check back and let us know how you're doing.
All the best,
