Chestpain, back pain.

A month ago i had sore throat with a low-graded fever, around 99F, then i had ear ache in the left ear. I was treated first with zithromax, my sore throat was gone, but i still had ear ache and hearing loss. then i was treated with amoxicilin for about a week, the earache is gone, but hearing loss is still here. at the end of the treatment, i started to feel nausea for about five days, and during the time i had trouble breathing, and felt my heartbeat increased occasionally. and around the third day i'm done with amoxicilin, my sore throat came back. i' still feel trouble breathing at times, and chestpain along with back pain (on the left side). The chestpain i felt is like i'm being stabbed by something, and it's all around the heart area.and i'm also very tired and lacking energy, mostly during the morning.  would this relate to a heart problem?
i've had chestpain before occasionally and i've done tests, such as ECG, that said it's normal.

To be sure that you didn't develop viral myocarditis you should have an echocardiogram done.  This can be ordered by a internal medicine doctor or a cardiologist.  However, this most likely is some type of a viral syndrome that hopefully will go away soon.  The fatigue and the palpitations are somewhat worrisome but not unusual.
