Whenever I go for a walk after dinner, for the past 3–4 days I’ve been experiencing pain in my chest, mainly on the left side. The pain starts off mildly but increases when I walk more. It radiates from my left chest to my left arm and reaches down to my palm. This pain has been continuous for the past 3–4 days. There is a slight discomfort in my left breast, but the pain in my arm and palm is quite intense. The pain increases if I try to hold or grip something.
