thank you for posting your query in healthcaremagic.com.... well from the history you have provided there are some possibilities which can cause the above symptoms like- eruption of wisdom teeth (your age is not given) tooth infection gum infection throat infection and lymph node enlargement jaw muscle spasm jaw bone or mandible problems all of the above can lead to jaw pain and headache also on the same side.... well but without proper examination it is not possible... so i would suggest you to visit a PHYSICIAN and if needed, he can refer you to a DENTIST or ENT specialist.... hope this was helpful... you can contact me for further queries... regards
