Had my follow up appointment today after trying to conceive for 1yr with stage 4 endometriosis. My cysts have returned and I will need surgery before starting IVF. However over the last 6 months pain has got worse needing regular days off work and GP says I can't have anything else. I am currently on mefenamic acid and co-codamol (30/500) which is not helping on bad days. So I asked the consultant today and he also said there's nothing else I can have! What do other people take for pain?
