TMJTemporomandibular joint disorder is a condition that primarily affects the temporomandibular joint. This is the part of the body where the mandible is joined to the skull’s temporal bone. The term actually refers to the many disorders that involve this specific area. One of the most common symptoms of these conditions is a sharp pain in the affected area. The problem itself may cause difficulty or pain while chewing, yawning, or even talking. For dealing with the pain and discomfort, doctors may recommend the use of medical marijuana. This can be especially useful during the post-op recovery process.
