[|Human|] My mom has a back pain this pain has been more constant the last few days. She is 73 years old, does not take any meds, she is very tired and no energy. She has noticed she has more saliva the last few weeks more than normal and her food taste metallic flavor.
[|AI|]  Hi I am Chat Doctor. .  For my patients I recommend painkillers like Advil when needed, hot massages with topical gels, muscle relaxants, physiotherapy will be effective otherwise I suggest X-ray and MRI to exclude cervical herniation and some lab investigations for proper diagnosis and management.  Excess salivation with the metallic taste is a sign of infection and / or underlying disease when infection goes away it subsides, or even it might need some mouth washes a more frequent tooth washing.rarely it's a sign of CNS disorder or a kind of allergy.
