Vivelle and hot flashes

I had a hysterectomy and developed nightsweats and hot flashes. The doctor gave me the Vivelle patch and I was fine for 3 months. I took it off for about 4 months until the hot flashes returned. I went back on it for a month and out of no where I started to have mini black outs. I also had neck pain, numbness and a dull headache. I was rushed to the ER after an episode and was checked out from head to toe. They could not find anything wrong with me. I had put a new patch on one day and noticed the symptoms getting worse. I have taken it off since and everyday feel better. The doctor's are not convinced it is the patch but I know my body and feel it is the cause of all my symptoms.

I have been wearing the patch for 4 weeks now. I am wearing the Vivelle patch to treat night sweats and hot flashes. It is working great! I have not sweats or hot flashes anymore. There is no noticable side effects other than I have not started my menstral cycle for yet.

I have been using vivelle dot for a few months now. It has completely relieved my hot flashes but I am unable to have orgasms now. Could this possibly be a side effect of vivelle? Maybe the dose is too high?
