<s>[INST] i just always feel shortness of breath, and Im realizing that I cannot hold my breath at all anymore. It makes me dizzy and feel like I am going to faint. I am a 30 year old female. No known health issues, except for some neck and back problems from a car accident years ago. I do have chronic pain, and frequent headaches from this. Can that be tied in with the shortness of breath ? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Holding breath can lead to legal nerve stimulation in some individuals. This stimulation causes vasovegal attack an Chat Doctor. Better not to perform breath holding in the future. I don't think any connection between car accident related back and neck pain and these symptoms (Breathing difficulty and dizziness). Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
