Hi, Had testicular cancer four years ago, and my testosterone was always borderline low (usually around 320). It came back at 270 earlier this year along with zero libido and low energy, so I started androgel 1.62% (2 pumps daily). I am also on 50mc Synthroid for an underactive thyroid. Androgel has helped with libido and a little bit with energy, but since I started taking it, it feels like I constantly have phlegm in the back of my throat and it seems to have aggravated my mild sleep apnea. Is this common? Is there anything to do about it other than to stop the androgel?
