My father is going downhill. He's had osteoarthritis for years (hips, knees, back) but recently following a fall it has become worse. He's already on Tramadol, but the pain is now keeping him awake - sometimes all night. I'm looking for something that would help him to live with the pain, and more importantly get some sleep; I believe he'll deal with the pain so much better if he can sleep. The big question for me is, is it advisable to work with medicinal cannabis in an 86 year old. I know for sure a nice Indica could give him some peace, but from experience it can also be a bit crunchy as it takes effect. What is the general advice here - is there an age limit? Have octogenarians been prescribed before? I'd appreciate any advice before pursuing. Thank you.
