Some guys get a lot of menopausal symptoms when they start T. You might be one of those guys. Definitely talk to your doctor, but I can share some of my experiences.
At a certain point in my cycle, I would get diarrhea. It was just a hormonal thing. It might also be a symptom of menopause, but you'd have to do some research or ask your physician. I know that digestive issues in general can accompany menopause.
I had an early menopause (thank the gods) before I started T. I had a lot of weird symptoms from the extreme hormone fluctuations. One was an inner-ear problem. I wouldn't get dizzy just walking down the street, but I couldn't maintain my balance when, for example, I got out of bed. I'd just fall back down on the bed again. Weird. Anyway, this symptom went away in a few months.
