My heart has been hurting including parts of my rib bones.

I’m having high fears of heart disease. I feel weak occasionally and I am terribly unhealthy. My oral hygiene is bad, I have high cholesterol for a year now, and I’m not too active with my body. My rib bones have been swelling over the course of a few months and been in pain. I even have excessive mucus with a tiny bit of blood and white mucus. And I can only feel my right lung and not my left. When I breathe deeply, I feel my right lung tightens a bit more than usual with a tiny mild pain. My average Beat Per Minute is 90.

You need to go to the hospital

Just went to the doctors and they said that the blood in mucus could be low humidity. Honestly I’m not sure what causes my symptoms anymore.

Maybe if someone is having high fears you should give a bit more to say then just "you need to go to the hospital."

I'm not a doctor but given all this persons symptoms that would be the logical thing to do. Wouldn't you think?

Maybe give your reasonings as to why you think this person should go to the hospital. Just putting that sentence seems more frantic. Also could put the person in a panic or make them even more uncomfortable.
