As you have had a hysterectomy, you will more than likely need Oestrogen of some type.
Your options for transdermal HRT, are essentially patch, gel or spray.
Then obviously there are various oral types which come in 1/2 mg doses.
You are the top of the licensed dose of patch at 100mg. If you are still symptomatic on that dose, then you would need a referral to a menopause specialist, for further advise. Specialists can prescribe higher doses and monitor with bloods tests, 3 monthly to check for absorption. 96 on a 100 patch suggests you are not absorbing well and you also have symptoms.
Some women find they need to top up their patch with gel or spray, to get relief.
Your Oestrogen level needs to be within a certain range, to protect your bones, brain and heart and I’m pretty sure if you google Chelsea and Westminster hospital, under the menopause section, they say around the 200 mark.
Definitely get back to your GP to start the ball rolling for a referral to a MS I would.
Perhaps give the testosterone a trial? A tiny blob a couple of times a week?
Best of luck 🤞🤞🤞🙂
