I am 73 7/o white male, with multiple health issues; recently hospitalized for cellulitis. Since lunch, I ve had little to eat or drink, But due to prescribed Lasix I have peed all afternoon. Just a short while ago, I began to feel uncomfortable. No sweats, pain down arms or jaw. It is SORE when I press on my chest. Afraid to be a fool and go to ER for excess gas, etc. Concerned it might be an impending MI. What do yi=ou suggest I do. My regular family MD is off for the weekend. Hospital is staffed by Asian MD s (hospitalists). Talk to me, please,
