I have had slight nipple irritation for the last two days. They are not sensitive when I touch them, but just sitting or standing I feel a slight tingle maybe you could call it in one of them. I do not feel any lumps or anything like that. I never really paid attention to how my nipples looked before so I can't really compare. I take liquidex .5ml EOD (currently on 500mg test e weekly/2 injections) What are some things to look or feel for, or watch out for? I have nolva and clomid on hand as well.
