That type of chronic pain is a tough one. I have 2 herniated discs in my back so I can sympathize. I think a large part of the pain relieving benefits occur because you are relaxed and distracted from the pain because you just all around 'feel good.' So other than to say 'something potent' and probably an indica I don't have any more specific recommendations.
Debrya, to . We are glad that you are here. I believe that this Pain Cream using only 2 grams made many times could be very beneficial to you for pain relief. We have members that have other recipes also. Look around and have fun.
