Hi poppy, I think I replied to you not so long ago about this problem, I feel your pain as I'm the same, unfortunately hrt has not taken it away for me, mine can be constant for months then disappear for months, I get the whole being so tuned into the feeling as I do that and it definitely makes the feeling worse , hrt could help you as I've read that during menopause the eustachian tubes narrow causing congestion which in turn causes dizziness, but also estrogen in the form of hrt can cause congestion which it has for me, I constantly have a full/blocked left ear, sometimes with pain, it always makes me lightheaded and like you I don't feel safe, about the fibroids I wasn't allowed hrt because of them as estrogen can cause them to grow, but mine were extremely large and I had constant heavy bleeding and resulted unfortunately in a hysterectomy for me and at age 43 isn't the outcome I wanted, but that doesn't mean its the case for everyone some can use hrt with fibroids so long as it's monitored I think, maybe someone with fibroids using hrt might comment if they are small and not causing problems, have you had a recent scan to see how many or how big they are?, sorry I don't have a solution to your problems but just wanted to let you know your not alone, hopefully you will get some answers during your ENT appointment it could be something not related to hormones, best of luck and hoping you get some answers and much needed relief x
