Hi there Imahotep! Oh wow!! the first sentence of your post says RSD causes arthritis! I never knew this?? makes sense though, after thinking about it!! cod liver oil? can you get those in capsule forms at GNC stores(Health stores?)I am taking fish oil. I am on Fentanyl 75MCGfor the pain, and tylenol #3 or 2 tramadols for the break through pain. The pain is still there, I wonder what it would be like if I took nothing for pain?? "A HUGE OUCH" on that! what meds are you on? Well, take care and thank you for this eye opener about RSD causing arthritis!! ~Love, Desi
