<s>[INST] I have twitching in my veins at different times of the day randomly, with no regualrity, I get high blood pressure only when I drink which is about 2-3 times a week which I consume about 10-12 shots of vodka every time...i have been doing this for about 6 years stright, the twittching in my veins could that be a sign of a serious heart condition? [/INST] Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that the twitching in your veins does not seem to be related to any serious medical disorder. Anyway, I would recommend performing a cardiac ultrasound to exclude aortic valve dysfunction. I would also recommend performing thyroid hormone levels to exclude thyroid dysfunction. Hope you will find this answer helpful! Kind regards,  </s>
