okay im on sustanon250 cycle at 500mg's per week, ive done 4 shots, so im going on my 3rd week coming up, and ive read some post on this, but i want some opinions, i dont know if it is my mind fooling or tricking me or what?? ,

my right nipple, when i poke it into me, sorta hurts, but there is NO marbles under my nipples or itchyness or anything like that. it is just when i poke at the right nipple and push the right nipple into me , is when it hurts.
the left nipple is fine.

should i start nolva or just keep monitouring them(nipples)??
and if i start nolva what dose and for how long?

thank you for the help!!!!!!
