Sammas - for quite some time - 3/4 years in peri I got bad ear ache and a strange pain in my jaw and teeth just below my nose.
I got treatment for sinusitis, ear infection etc etc but nothing stopped it. I went to my dentist who said I was grinding my jaw in my sleep. I had terrible, terrible anxiety and panic attacks during peri and these only stopped when I got on the right hrt (long long story). Anyway, since the right hrt no earache or jaw clenching except when exceptionally stressed and it only lasts a day now instead of being pretty much permanent.
Like CKLD says the muscles get lax and you can get weird aches and pains all over the place due to the fall in oestrogen. I have never had coccyx pain but my knees and ankles got so painful at one point having them touch the bed when I lay down was pretty bad. Again when my oestrogen levels got ok, it all went away. Meno can throw up all sorts of weird stuff!xx
Welcome to the wonderful world of meno!!!
