It doesn't help we are living in days of the caveman as far as research goes in the U.S. Oddly enough the only money the U.S. will pay for is to find fault with cannabis, never for positive research. Almost every study ever done to show damage has been disproven or challenged. However saying that, some of these limited often bias studies have shown that it does not work for everybody, and there are in fact some side effects and some drugs interaction just like every other medication. Some of these include CBD not just THC. Biggest one being a blood thinner like many spices. The good news is there must be a drug that works for you, given this one doesn't. Or a couple in tandem that might work. My dad had extreme anemia after trying just a salve, being on a blood thinner. Getting older everything changes, so we might need to change our intake and slow down on things. What ever works even if it's just music, fresh air, a loving pet, warm bath, or ice pack for a few minutes. There is relief!
