Next step in high CPK levels

[ScarlettMLynn]

Around April, my fiance lifted for the first time in a long time. He is 24, and has been active throughout his life. The next day, his arms were swollen, which was expected. However, the swelling persisted and proceeded to swell two inches larger than normal, to the point where he could not straighten his arms. His eyes also began to swell. We went to the ER after he developed a rad patch on his bicep. They checked his enzyme levels (CPK) and they were through the roof (~15,000). They tested his kidneys as well, and they were fine. They originally suspected rhabdomyolysis, but ruled it out. The final diagnosis was a possible viral infection after he passed a nerve test. They flushed him with sodium bicarb, and gave him a regular IV and he was released after 3 days. He followed up with a specialist (which I am assuming they just tested his blood for his enzyme levels) and they told him he was ok.

However, today (July 1) was the first time he attempted lifting again, extremely light. He came home and his eyes were swollen yet again. I am not sure where to go from here. I realize that it is difficult to diagnose from a simple message, but I was hoping you may have came across something that may sound familiar to you.

Should we consider an endocrinologist? I am just scared and feel as though the protocol for his symptoms was handled poorly. They were only focusing on his enzyme levels and not the underlying problem. The next step was a muscle biopsy, only if there was an abnormal result with the nerve exam.

I appreciate any advice you have to offer. I am just concerned, and I have no clue where to go from here.
