<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi , for a few years now I constantly now and then have a weird tightning sensation which seems to be feeling like its on my heart as if someone was squeezing and tighning it , It does feel like its more to the left side of my chest and I understand the heart is directly in the middle of your chest , but I can honestly say it feels as if it is the heart , I am getting worried as it seems to be getting worse , I try to go to my gp but all I ever get told is it cannot be my heart etc ... What do you think this sensation could be ?  <response>: Thanks for asking your query completely understand your problem this tightening sensation can be due to a variety of cause in which gastritispeptic ulcer is common cause in young age and that can be dealt by taking some proton PUM inhibitors like pantoprazole, if youre worrying too much u can have an echocardiography ECG done and consult a cardiologist which would be the best option and that will end your worries. Thanks may god bless you with good health if you have more questions feel free to ask
