Hello Doctor, I genuinely need your help. I am feeling little bittle pinching on left side of chest sometimes in a day, basically when I take neck stiffness medicines. Have done with my ECG three times in three months in 2021(June, oct, nov) and everything was normal. And i was effected with severe acidity in 2021 at the age of 22 and medicines are still going on as i am feeling tightness in left side chest amd general physician told me that it's nothing but gastritis problem. But now, sometimes i am having left hand pain as well. Please suggest, what should I do Is it related to heart or something else. 😔😔 Very tensed now at this age and i am solely earning member, that's why having more pressure on me.
