Friend is in the hospital - I am worried

I took my best friend into the ER yesterday. She had been having pain since Tuesday and it finally became unbearable in the early evening. She is having classic heart symptoms: Pain under the breast, pain down the arm and in the jaw, nausea, confusion (not all the time - just when the pain is happening) and several other things. They admitted her even though all blood work, EKG, and chest x-ray were normal. They have given her Nitro (which lessened the pain, but did not take it away today, but it helped considerably last night) and she is wearing some cream (I am assuming Nitro as well). They have her on Dilaudid and it makes her loopy but helps the pain. She is getting the sweats with the pain, and her entire personality changes (as in confusion and not knowing words). They gave her a stress test and I am pretty sure they found something on it because they kept her another day and are sending in a cardiologist.

I will be honest. I am very concerned. She has heart problems in both sides of her family, with episodes happening before the age of 50 (she is 59). She lives alone (well, with her cat) and I don't want her to have an episode at her apartment and not tell anyone (I had to almost convince her to go in yesterday, but thankfully the pain did that). She is scared, and so am I. I want her to be okay.

SoSt9,

I am sorry to read of your friends illness and I hope the Drs will soon have an answer to the cause of her symptoms.

Your friend is very lucky to have you in her life and I am sure you are lucky to have her - what are best friends for if not to care and yes, worry about each other when one is sick.  The best thing you can do is just be there for her and not let yourself become ill from stressing out about what is going on.

Gentle Hugs to You,

Kitt
