Hi Patsie,
was told by the ENT that I did not have enough saliva on my tongue.
I don’t feel there is less saliva
So although ENT felt you had too little saliva you don't feel that yourself?
I suffer from vaginal dryness, my skin is very dry too
We do tend to suffer from dryness with the decline in hormones at menopause, so what you're experiencing, though uncomfortable & unnerving, may be no more than that. I asked about HRT because I wondered whether if you'd tried it, you noticed any change in the dryness. I'm assuming you still have both ovaries? Reason for asking is because even postmenopause (as I think you say you are) intact ovaries go on producing a significant amount of testosterone, so that the relative androgen deficiency resulting from removal of ovaries is thought to be associated with some conditions that have dryness as a symptom (such as Sjogren's & Dry Eye Syndrome). Can I ask are your eyes dry as well?
I think several members have posted that they're trying sea buckthorn for dryness. If you have a google there seems to be some thought that it may help dry mouth, eyes, vagina etc. Topical HRT (Vagifem, Estriol cream etc) is very low dose & can really help with the latter if you don't want to try systemic.
