I hope it is temporary, but definitely reactions to medications.
Do not get any ideas!
I had a small routine medical procedure about 3 weeks ago. The first night of my recovery I wet the bed and have wet the bed every night since. The leading theory is a reaction to the prescribed oxycodone, but waiting on a visit to a urologist. At the suggestion of my doctor and a couple of other people, I started keeping a journal of what I eat and drink and how often I go to the bathroom. I have noticed a definite increase in urgency without a lot of volume. . .so there you have it. A, hopefully, temporary case of incontinence.
However, if asked by anyone but someone very close to you, I would just say "medical reasons" and that you are uncomfortable talking about it further.
