Have Had Migraine Headaches. Why Is There Neck Pain, Metallic Taste In Mouth Now? Connected To Root Canal?
Thanks for posting your query.
The pain and headache that you are having can be due to cervical spondolysis or due to it muscle spasm of the occipitalis and other muscles of the scalp. The spasm can be so intense that the muscle will feel bruised or sore even after the tension has been released.These muscle spasms then cause primary headache like tension headache.
Apply alternate warm and cold compresses and take some over the counter NSAID analgesic(pain reliever) like ibuprofen(advil/motrin) or acetaminophen after consulting your doctor. Application of muscle relaxant to the part is also helpful. If there is no relief then get an X-ray of the neck done to rule out any cervical spondolysis.
Metallic taste in the mouth is caused by caused by anaerobic bacteria that live within our bodies. These bacteria can grow in number very quickly when given the right environment or food source thus causing a bad taste in mouth.
It can be due to dental caries, gastro-esophageal reflux disease, medications like antibiotics, vitamins and antidepressants, poor oral hygiene etc. Are you taking any antibiotics like metronidazole or tinidazole?
I suggest you to get an examination done from a dentist and get dental caries and GERD ruled out.
