What Causes Hot Flushes Along With Red Itchy Lumps On Hand And Foot?

I am 55 year old woman and for two years and eight months have had very hot wet flushes every hour. Have tried Kliovance for one month then Evorel continpatch for two days - same reaction with both - red itchy bumps on hand and foot. Also very tired and bloated feeling. Dr advised stop due to rash each time. Now becoming desperate. Shall I try patch again or maybe even at our private Mcindoe centre bio identical which the specialist says is risk and side effect free?
