So...
had my appt with HRT consultant. I was told that my oestradiol levels are still too low and that to get the full benefit from HRT, needs to be at least 250. I have been prescribed 100mg patch, with repeat bloods in 8 weeks. I asked about oestrogel, since that's what the nurse who runs the clinic's patent helpline had suggested, but consultant thinks patches are better as they give a more consistent and measured dose than gel. She also thinks my high prolactin level could be inhibiting my oestrogen absorption. I need to follow this up with my endocrinologist. I may start a new post about this, so I have some grasp of it before seeing endo. In meantime, thanks for your replies and good luck. I will persevere a bit longer.
Kathleen - see above, I was told oestradiol needs to be at least 250 for optimal results. My GP wasn't able to interpret my results at all. Personally, I feel much happier having my HRT managed by a consultant, at least until things are stable.
Matilda mouse - yes I am using the 200mg progesterone pessaries (Cyclogest) every night. Consultant advised me to use continuously. I did query the dosage when I switched from Provera 5mg tablet. I as told that as its a micronised form of progesterone, the dosage is quite different and not comparable. I do also have ME, which I have had for years, and poor temperature control has always been one of my symptoms, so the sweating could be related to that, i suppose.
