<s>[INST] I m experiencing achy ness in the left side of my neck all the way up through my jaw bone and into my ear. I have been taking ibuprofen to keep the pain or inflammation down. Sometimes I think it may be an irritated tooth however just contacted my dentist and there was no suggestion on the x-rays taken Dec 30. So don t know if it could just be a strain or possible sinus infection. However very uncomfortable. suggestions??? [/INST] Hi..Thanks for your query.As per your complain pain in jaw, neck that is radiating up to ear can be most probably due to causes like wisdom tooth infection or inflamed gum flap over wisdom tooth that can cause radiating pain to jaw, ear and neck..Other common causes can be due to Temporomandibular joint dysfunction syndrome..It can also be due to other causes like pulled muscle in neck, spondylitis, ear infection etc..It is not appearing due to sinus infection as sinus infection is associated with other symptoms like post nasal drip, facial pain and pressure, nasal congestion etc..So my suggestion is to consult an Oral Pathologist and get evaluated and a thorough clinical evaluation, appropriate x ray can help in diagnosis..If there is no dental infection ruled out then you will be referred to a Medicine Specialist and an MRI can be advised to rule out the other causes and treated accordingly..As of now you can take painkillers like Advil, Naproxen etc to relieve pain..Hope this helps..Regards. </s>
