Can analgesics, nitrates, and antifoaming agents manage acute chest pain?

Hello doctor,

I am a 24-year-old female currently experiencing a respiratory and gastrointestinal illness. I have been feeling faint, especially when going up or down stairs. My other symptoms include mild, infrequent shortness of breath with a peculiar sensation in my chest (similar to breathing in very cold air, but not cold), occasional dry cough, reduced appetite, fatigue, especially after any exertion (despite trying to rest with two young kids), bloating, runny and sore nose, and mild muscle aches. In the past, I used MDMA. Currently, I am taking Cetirizine dihydrochloride, a multivitamin, omega-3 supplement, and a combined oral contraceptive pill containing Levonorgestrel and Ethinylestradiol. I think I should mention that I am breastfeeding a toddler who is also sick, but I have been drinking plenty of water and eating despite the loss of appetite. I walk every day and eat healthily, including plenty of fruits and vegetables.

Thank you.
