Feltys SyndromeFelty’s syndrome is the term used in reference to a number of debilitating and painful conditions that include a swelling in the spleen, reduced white blood cell levels, and recurring infections. Most of the symptoms of Felty’s syndrome mirror those experienced by patients with rheumatoid arthritis. The condition commonly results in stiffening and swelling of the joints. Patients suffering from these conditions tend to benefit from the pain relieving qualities of medical marijuana.
