Hello, im a 21 year old male, have an active lifestyle and i take care of my health. I have been having problems with my muscles. Whenever I work out my arms get huge, as in 3X's their size (which is kind of cool to see!) but is far from normal. Then within a few hours the size of my arms decays so much that my arms are now smaller than before. Later on that same day, i have stomach aches and feel kind of messed up, like my intestines are having to process a huge meal. I have been getting quick, brief, and powerful headaches to both the front left & right side of my head. And now both my hands each have their own tint of blue to them, like getting little blood flow. I have been working with the doctors alot, but none can give me a diagnosis! I have taken no drugs or stimulants, nor been exposed to anything that i know of and have no family history of anything like this. I have been told to stop working out by my doc's as to prevent another muscle trigger. I'm kind of scared about what this is and would like to here any help that some may have.
