There are 3 main categories of pain, Nociceptive, Inflammatory and Pathological. Nociceptive is the most common, triggered when receptors on our skin or internal organs detect harm. Inflammatory pains are caused by the body’s first response when healing an injury, such as a twisted ankle or sometimes by chronic conditions such as gout and rheumatoid arthritis. The last group, Pathological Pain is caused by damage to the nervous system or by its abnormal function such as Neuropathic pains, (nerve damage, multiple sclerosis, strokes), and Fibromyalgia.
One medical study was done to see the effectiveness of CBD for treating pain caused by operations, and it was discovered that CBD had an effect on pain suppression but also altered the way the subject perceives pain, reducing the emotional impact it has.
