About a day ago my niplles started feeling a little sensitive. When i touched them they had a small tingling feeling and it hurt a little. I dont see any differences at all physically. And it only last for an hour and then they feel normal. Am i being just too paranoid? My friend suggested Tamoxifen Citrate. This being the same as Nolvadex, just its in liquid form. And if this is the beggining of gyno, should i take 20mg daily?
