You sound as though they did take your ovaries, and or the surgery has shocked you so much your ovaries have shut down.
Are you having terrible sweating, I had some kind of reaction immediately, in the hospital 24 hours after surgery, told it is rare, started sweating like a waterfall, nurses had never seen anything like it, soaking bed clothes through and through, and I couldn't stop, I say to my friends my fingernails sweated, you could see the sweat rising through them, they could not keep drip lines in my arms open as my veins keep collapsing, came very close to really serious problems with dehydration, Dr's standing by to do cut down to realy big veins, when they got one drip to hold and stay open, put on computer pumps to push enough fluid.
Eventually they figured out I had some kind of hormanal shock, they did take my ovaries, as I had a endometiral cancer, diagnosed with D & C.
Put me on HRT, that I did not like, but it brought it under control, took me off after a souple of weeks and the sweating, shivers and shakes came back, so back on HRT, slowly slowly over the next two years I was able to wean myself off HRT.
With hind site, the shock of diagnoses, the surgery, Dr's taking my ovaries, pain killers, and urine infection, body over reacted to everything, incl flash addicting to pain killers, had to step down off those as well as recover from surgery, re-admitted in agony and vomiting, same day as discharged, until young Dr figured out what was going on, replaced pain killers and agony & vomiting stopped, that confirmed his worst fears that I was addicted, not suggesting you may be of course. At ten weeks I would think your heavy pain killers would be to a minimum now if not gone.
5 years later have had double hip replacement, no problems with pain killers, other than being very sick, vomiting on morphine, they replaced with different drug, no problems with addiction.
The hospital did raise the issue, as they had it on my file, big interview about what I was going to do if I found myself in the same situation, very matter of fact answer from me was I would have to go through the step down process again as I had previously with success.
