I have chronic back pain and also rely quite a bit on anti-inflams. In my case, my pain goes into remission during pregnancy, but makes up for it after bub arrives . Now that I am breastfeeding, anti-inflams are a big no-no. My doctor suggested I try Panadol Osteo, which have definitely helped. They are a lot stronger than panadol and are slow release (over 6 hours). I am not sure if you can take them during pregnancy, but given that they are only paracetamol, you may well be able to. Perhaps ask your GP or the chemist? They have really helped me a lot! I can sympathise and hope you find some relief for your pain.
