Yep. We can help.
Make a list of your worries to take to the appt. so that you don't forget anything. It may be a small fatty lump that you are feeling rather than anything sinister. Getting a hands on exam by a Doctor is the starting point. My lump was removed in the 1990s, still here. My biggest worry was that the regular appts. would cause panic attacks
As for itchy nipples, one of mine gets like that so on goes either 'savlon', a hand cream, talc which eases as I can't scratch, in fact I can't bear to touch my nipples
. Hormones can cause all kinds of weird feelings. As oestrogen levels drop off, the body may become dry: inside and out; scalp, deep in the ears, eyes, vagina, skin ........
Periods wax and wane. Some become heavier, others lighter, intermittent .......... The Change, does what it says on the tin! Some find that keeping a mood/food/symptom diary useful. Let us know how you get on?
Make a note of the HRT - perhaps put the name into the search box on here to see what pops up? Make notes ;-)
