Do you have insurance? If so- go to a doctor. It's that simple. Ask the doc to take blood test, tell them your symptoms and any dug/steroid usage. Your doc isn't going to do anything if you tell them you used clomid or a cycle- but it may signal that you've messed something up that they need to fix.
I'm curious- how do you know your blood level of T and estrogen if you don't use pharm enhancement? Usually, only those that use would get tested- making sure they are in optimal ranges. If I were natural (just got placed on TRT), I wouldn't test myself- what would be the reason? Nothing I could do about it anyways- and it would save me about $600...
If you are truly natural, then I would say your above symptoms are from overtraining- seeing as how you were training for competition and all- probably low water content and sleep deprivation too. But that usually culminates into a lowered immune system and catching the flu or any other germ that's rampant in gyms. Also, I don't know any natural lifters that will pop clomid post competition bc they have symptoms as yours.
Just make sure if you do see your doc, you tell him/her the truth. I'm not saying you're lying OR telling the truth- it doesn't matter to me. I just want you to get better.
