I have BP DO, GAD, and PTSD!

I have BP DO, GAD, and PTSD. I recently started a low dose of Klonopin for neurotic excoriation (scalp and fingers) due to exacerbation of GAD. 3 days after starting the med, I went to the ER with a strange itching,burning, swelling in my left pectoral area. Aside from obvious muscle inflammation noted on a CT scan, and a CK of 10,000, everything was normal. I did have a weight workout 5 days befor eany swelling presented. Neither the ER doc nor the Admitting MD at the hospital I went to knew what happened or why. They put me on IV fluids and Ancef empirically. I was discharged the next day with no diagnosis and a CK of 7,000. The swelling in my left pectoral muscle is dissipating (it's been 24h since D/C). I called my psychiatrist, and she feels there is no correlation b/t the Klonopin and my symptoms. I have noted an increase in agitation/irritibility with Klonipin.
PMH: Asthma/Environmental Allergies

My VS are great, BP range b/t100-110/68-78. - no Hx HTN, no statins
Meds: Trileptal 900mg daily
Celexa 40mg daily
Singulair 10mg daily
Buspar 15mg daily
MV with Fe
PRN Ibuprofen

2 weeks prior to ER visit I had SOB, 1 week prior severe headache upon awakening. Day of ER visit I had neither. I associated the SOB and Headaches with an anxiety response. This is why the Klonopin was ordered.

Running a low grade temp (99.3) again today, mild pruritis left pectoral area. No rash has been present with itch.

Any ideas? Is Klonopin the culprit? I intend to have a Cardiac Stress Test as soon as I can f/u with my PCP. My father had his first MI at 32.

Thanks for your time,
