<s>[INST] Good evening. I was diagnosed with disk herniation in C4/C5, 3-4mm, C5/C6, 4-5mm, and C6/C7, 6mm. I am doing some physical therapy to try and help reduce the inflamation that is causing the neck and shoulder pain. Along with the pain, I ve had numbness and tingling in my left index finger and thumb along with heart palpitations - where it feels like my heart is skipping / missing a beat. I m a 45 yo male, otherwise healthy - don t drink, smoke and keep my weight in check, etc... Q Are the heart palpitations something I should be concerned with? Is it caused by the C6/C7 disk herniation sending electrical signals incorrectly? Thanks, in advance, for your assistance. [/INST] Hi, If you have not been identified as a high-risk factor for heart disease and live a healthy life as you say then, I would not worry about that aspect of things right things. Sounds like you're doing the right things. The cervical bulges/disk herniation are entirely unrelated to how the heart maintains its rhythm or speed.  Those functions are mediated by nerves emanating from the brain stem cranial nerves as well as through the Chat Doctor.  Hope I have answered your query. Let me know if I can assist you further.   </s>
