I have been on x4 pumps Estrogel for 8 months, suddenly, hot flashes after feeling great and no flushes since HRT patches/gel 4 yrs ago. Blood results went from 380, to 1,400 to 2,300!!!! all over 3 months, and now I am in despair-nothing is working, swapped to 100 Evorel even worse flushes, and x3 estrogel, OMG!!!! NO sleep, flushing all night. Now what? back to x4 gel, still sweating but not as horrific as x3. Tiny amounts of T gel as GP thought it may be converting to E, and Norothisterone for 10 days as Utrogestan did nothing to stop spotting. Also changed to x2 AM and x2 PM of O gel, it hasn't made much difference. Look 100 today, red sore eyes from the Norothisterone, and generally in complete despair. So much so that I took some DHEA to perk myself up. Any ideas?
