I think what has helped my husband the most to understand it to see the difference I had with pain control, He still does not totally understand but he can tell by what I do and how I act when my SCS is not working. Couples counceling helped for a short period of time but he tends to revert. He is also Bipolar and does not take his meds so he thinks I should not take any medications for my pain or my depression. He does listen to a friend of both of ours who is also my PCP. When he tends to "forget" I call our friend and he will remind him about my status and the fact that my pain and depression are both real
Hope it helps to know we understand!
