Hi Dougal.
I'm sorry to hear your problems.
I can't comment on the endometriosis nor the ablation, but the VA is quite normal.
Didn't the doctor offer you anything for the VA?
There are creams available, either on-line, or you can buy from Boots, = yes products, Vagisan, a number of different creams are available to help with VA. And they really do help.
I'm sure someone will post soon who has been through the same as you. Take care. Xxx
