<s>[INST] Hi, my upper spine clicks whenever I breathe in. It creates popping noises which are disturbing most of the time. I do not feel any intense pain however, only discomforts whenever they crack. Is this abnormal and what can I do to improve the situation? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Yes, this is abnormal. This suggests instability of cervical spine. This is commonly seen with cervical spondylitis. It is inflammatory disease affecting intervertebral discs. So better to consult orthopedic doctor and get done clinical examination and MRI of cervical spine. You will need calcium and vitamin D3 supplements. Cervical collar or belt should be applied all the time. This is to prevent mobilization. Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks </s>
