Hey Bro! That is normal. I had the same problem after I came off my cycle, about 1/2-1 week into my clomid my elbows started to really hurt and they would always crack and pop. I upped my L-Glutamin intake to about 30 grams a day and started to put icy-hot on them. I am now starting week 3 of my clomid and the pain is almost all gone. Best of luck!
