I had a shoulder problem and couldn't lift my arm above my head. Made it hard to wash my hair. I started taking Zatural Cannabis Broad Spectrum CBD oil 300mg. Not long after taking CBD I was able to start lifting my arm above my head. I have not had any problems with it since. I ordered some more of the same product thinking it would help my joint swelling in my fingers due to my Hashimoto. I wasn't able to take it cause it would have interfered with my thyroid medication. I know it probably would have helped with my joint pain. The customer service at Zatural are wonderful!!! They can answer all your questions. I would recommend them to anyone.
