<s>[INST] I had left shoulder pain which spreads throughout left hand since two years.Ihad many ECG and even TMT but could not found any positive report.Is it survical pain? my heart beat sometimes skkiped which makes me afraid.I have diabetis and high blood pressure also.I takes medicines regularily.Please suggest me what should I do? [/INST] HAI.normal ECG and TMT shows u don't have a cardiac problem. U can have problem of cervical spondylitis or cervical disc problem like compression or prolapse more on the left side, due to which your problem has more radiating pain on the left side. These things can aggravate more due to hypertension and diabetes. Pis check out with a MRI cervical spine and shoulder joint, Irregular pulse rate can be due to the same reason or due to hidden thyroid problems also.pls continue with regular medications can start with pregabalin/gabapentin added with methylcobalamine. Take care. Good luck </s>
