Can migraines be on both sides? i have really bad tmj and i have been getting a tension type headache, watery eyes, facial pressure/pain. i also get muscle cramps, spasms in my one temple when i have a flare besides my jaw/cheek. or is this tmj flare?

Your question is challenging. Migraine can be on both sides, but tension headache and and tmj can give pain In similar locations. If you have other symptoms like nausea, visual changes, or neurodeficits , migraine is likely. If your pain is frequent and/or severe I’d see a neurologist who specializes in headaches.

Obtain a dental consultation, perhaps from an Oral Surgeon, to correlate jaw issues with the full symptom complex. You could have both, with migraine as a co-morbidity. Once dental issues are excluded, a neurologist should become involved.
