No real input here other than to say that some cysts are painful, others are not. When I had my hysterectomy, they told me I had sings of having had several cysts on my ovaries. News to me. Never had that type of problem. Most cysts are benign, non painful, and go unnoticed other than the symptoms they offset in other nearby organs/placed.
As to your suspicion that it could have been something other than a cyst; anything is possible. I can't imagine having surgery, being gone overnight, and not telling my H unless I was hiding something. To each their own.
