Hi there. One of my sternocleidomastoid muscles is larger than the other. It has been for years but seems to be getting larger. I also get muscle spasms on that side that leads to some anxiety because it feels like there is pressure on my throat. Is this common? Should I have neck massages? Thank you for any input or advice!

Hi I did review your concern. I would advise you to get evaluated by a doctor as to why the muscle is larger. Is it the muscle that is large due to fibrosis or hypertrophy or thyroid gland enlargement or there is a vessel behind it that is causing it or there are nodes enlarged? A proper examination of your neck is warranted. If needed an MRI scan of your neck may be needed to see the exact cause. There is treatment for each of the conditions mentioned above and treatment is different for each. The large muscle can cause pressure on your throat If there is a swelling then a needle aspiration cytology may be needed. I hope this helped me know if you have any more questions or concerns. Wish you all the best.
