Thank you Rachel, you are very helpful. Yes tonight I will try some THC to help sleep and hopefully take away a little pain. Will start off with a little and experiment over the next several days/ weeks and hope to find what works best. I am also trying the Dr Ho’s TENS circulation promoter, although I’ve only had this gizmo for two days now so I certainly can’t give any kind of feedback as yet but I did find the first night of sleep after an hours use seemed to be a little better quality - reduced pain, longer sleep for example but I do need more time to assess its effectiveness. I am sure these devices have been discussed a lot on here. Take care
