[|Human|] Hi, my name is Cliff. i am currently having this problem. my vein on the left side of my head is pumping very hard and fast, when i put my fingers there i could feel the thick and big veins there. very painful and it is only on the left, it happens to me on and off, which i have reasons to believe it could be due to lack of sleep? or stress? please help!
[|AI|]  Hi and thank you so much for this query. I am so sorry to hear about this pain on the left side of your head. It is true that we have big vessels there that pump hard but rarely can they contract to cause significant pains as you have mentioned. However, muscles in this area can exhibit spasms which explain most of the symptoms that you are having. This can be aggravated by stress, lack of sleep, poor head positioning, etc. You should get these conditions' ad Chat Doctor. I hope you find this helpful. Thank you so much for using our services, and please do feel free to ask for clarifications if need be. I wish you the best of health.
