Hi Dear , Welcome to HCM. Understanding your concern. Thanks for your query . Yes symptoms you mention in query are caused by problem in temporomandibular joint (TMJ) . There can be many reason that can cause problem in TMJ like excessive opening of mouth , wrong movement of jaw during chewing or speaking ,condition like arthritis or any tooth related problem. The condyles of TMJ slides on a disc like cartilage in most of the cases cartilage become inflamed and cause pain and restricted movement. I would suggest you to consult dentist for proper examination . Doctor may order X-ray or CT scan to find ot what exactly causing the problem and treat it. doctor may guide you for correct bite or grinding habit and may give you night guard . He/she may perform procedure like arthocentisis to remove inflammation debris or correct if there is any dental defect. In some cases doctor may also perform surgery to correct any anomaly. For now keep warm compresses to affected area several times a day ,take over the counter medicines like aspirin or ibuprofen for pain and inflammation and start physical therapy of jaw .
