What Causes Upper Arm Pain And Tightness In Chest After Foot Fracture?

Question: I broke #4 & #5 metatarsal bones in my right foot 10 days ago. The last 4 days, I have been experiencing severe upper arm pain and tightness in my chest. Two nights ago I went to the emergency room because I had extreme burning feeling around my heart and in the back of my neck going up to my ears. Also, I have been experiencing joint pain in different unrelated joints. My arm pain was still extreme. They took x-rays of my chest and gave me a stress test and said I was fine and sent me home. I am still suffering with the same symptoms. Last night I began coughing and the extreme pain in my upper arms went down to my fingers. The bones hurt for hours after and my fingers were ice cold for about an hour. Today, I am still having the feeling of pressure on my heart and my arms are still hurting all the way down to my fingers. I have been taking ibuprofen every 6 hours without getting much relief. I do not like hospitals or going to the doctor but my husband thinks I should go to another hospital. I am generally very healthy and active so this is new to me and I don't know what to do. I don't want to all of a sudden have a heart attack or stroke. Have you heard of anything with these symptoms?

Should I then go to another hospital to have these tests o should I go to a doctor. If to a doctor, what type of doctor?

Thank you!
