“Collarbone swelling”

Cervical issues can cause the pain, but should not cause localized collarbone swelling.

At least from the brief description you're giving me, yes, this can be a possible reason why. However, what I have learned from decades of experience seeing hundreds of such presentations is that it is never just one reason, but overlapping issues to create this type of clinical picture. The way you are describing the pain pattern, this pattern can be seen in radiculopathy (where spinal nerve roots are affected). The "lump" you are describing can occur when the nerves are irritated and lead to the muscle either "guarding" as a protective mechanism, and given enough time becomes "dystonic", which is a over compensatory sustained contraction or "guarding" mechanism. However, if you go to an experienced Neurologist, they will be able to examine you clinically to truly see if that is one of the multiple reasons why you are having these manifestations or not. I would not recommend trying to figure this out without consulting the right medical expertise. They should hopefully also be able to give you several effective non invasive options to help heal and prevent this, and/or determine if you truly warrant surgery. I would not take any surgery to the body lightly, especially when it comes to the spine. There are short term consequences and then there are long term consequences one should weigh before committing to such decisions. Keep in mind that doctors and patients are like Cinderella and the glass slipper. Go with one who feels like they are the best fit for you and with whom you feel confident enough to develop that trust. You can have the "best" doctor, but they may not be the best doctor to help you in your journey to healing. Honestly, I love patients, like yourself, who are proactive in caring about their health because those are the patients that ask questions. I hope this was helpful. Thank you for reaching out. -Regards, Dr. A
