I had a total thyroidectomy 8 months ago and I must admit , most of the time i forget to take my Synthroid pill. I have noticed that i get a yeast infections often now. I mean the week b4 my period the week after my period and when i am yeast free if i were to have sex with my hubby , i would get irritaded within 3-4 hours. I whent to gyno and she told me that it is normal for me to get it b4 and after my period. But i never use to have this b4. b4 my surgery i probably have an infection once a year!! now I am lucky if i can be yeast free for at least once a year ! I thought it was my hubby, but he is all well. Can my surgery be causing this?
