I am in quite a similar situation,having had all the medical treatment options that can be given and also at 48yrs not allowed anymore GNRH drugs.You can have more than 6months of GNRH agonists as long as you agree to add back HRT.I had 2 years of decapeptyl and 1 year of synarel,but had to have hrt which I always think is a no brainer.I had absolutely no pain for the 6 months without HRT,but on the patches had pain and mood changes,then got a suspected pulmonary embolism,so was immediately taken off both the decapeptyl and the HRT.
None of the drugs are cure,only supress periods and allow it to shrink back,but as soon as you come off them the body and brain goes into overdrive and causes massive hormonal surge in oestrogen and we are back in agony.
It very much depends on your age,whether you hope for children or have completed your family.Many here have said mirena coil is very effective,others say proper excision by endo specialist surgeon is only way forward.I am being told to have total hysterectomy and excision,but am unconvinced re the hysterectomy.Take your time and don't be forced into a decision you may later regret eg hysterectomy.Others however never look back,so ithas to be a personal choice.
It is so very difficult ,but do your research and become informed about your choices.There are lots great websites that have been posted here -some traditional and others looking at holistic approaches.
I am seeing a herbalist ,nutritionist and follow the endo diet.This is not enough in itself,but I hope is making my body stronger by working on immune system,liver,digestion etc
know you are not alone and sending you a big hug.
