I thought I'd finally found the holy Grail with estraderm patches but after a few happy months I have slowly started to react to the adhesive to the point where I am now covered in bright red square patches of welts and constantly surreptitiously scratching... I gather this isn't uncommon but wanted to check, if others have experienced this does it go away if I stick it out? Will other patches like estradot give me the same problem? (And can anyone even get hold of estradot at the moment?!). I actually prefer patches to the gel but not sure I can cope with estraderm much longer!
