Tyson, I hope you are doing okay.

I think I know why you are in such pain. It IS the Accutane/Isotretinoin, I would bet on it.

This first article states very clearly that people with neuromuscular disease should NOT take it.

And while I hate to cite anything from wikipedia, here it talks about what Accutane does to your telomeres. They are so important and Accutane does affect them.

If I were you, I would send that first article to your neurologist, dermatologist and internist. I would get the heck off of that drug and find an alternative to acne. There are reports to the FDA that there has been irreversible muscle damage done due to this drug.

Has anyone even tested your serum Vitamin A levels to see if you have a toxicity of it?

And they SHOULD be testing your CPK, as Nicky so thoughtfully pointed out.

And what if your headaches are intracranial hypertension?!!! I think you should NOT exercise until you have this figured out!!!

Some common sense needs to prevail here. Your HEART is a muscle too, you know. MG may not directly affect it but Accutane can.

PLEASE take this seriously. Damage may already be occurring to your DNA and your muscles.

I hope you will do a search on causes/alternative treatments to acne. Please take it easy.
