Hi Allison, I understand your pain and frustration. I also suffer from Endo and Ando. I personally have not tried any injections for pain relief, however I have tried the pelvic floor therapy. In addition to that, I think you should invest in a tens device. What this device does it stops the pain signals from going to your brain. The brand I use is called OVIRA. The device is under $150.00 and you can do installation payment. They also send you an invoice that you can bill to your insurance for a possible payment. I hope this information helps.

I used to be in constant pain too and low dose naltrexone totally broke that pain cycle in me. LDN has very few side effects: some headaches at first, more vivid dreams, sometimes weight loss.

Hi👋 ,
It might be a bit different as I'm in the uk with paying for treatment but I have tried lidocaine for pain related to endometriosis and adndo. I'm stage 4 it's compleatly stuck all my insides together and I have pain in my thighs, groin, bum and in the general lower tummy area. Before I was put on prostap injections I had diclofenac suppository that would give me a little break from the constant pain when I was on my period but wasn't sufficient enough. I have tried lidocaine and found that to be very helpful. I used patches of lidocaine and never had any side effects from it.
Endo is different for everyone and I feel that if you are suffering and there is side effects from medicatin you have to weigh up what the best will be. I was terrified to try anything but the pain and lost time in work and with my kids and family just made me try any suggestions the dr gave me. I hope you can find some releif and I hope my story was a little bit of help 🙂
