What causes tingling in only one side of tongue? I have just that symptom that is all. Could it be MS or anxiety? Ms could do that single symptom?

Yes but.... While ms could theoretically cause this isolated symptom, as a male of 29 years of age it probably is not ms and is, as you say, just anxiety. If the symptoms persist or if you notice other similar neurological symptoms you should see your doctor.
Not MS. Recommend dental exam, as most likely this is a localized problem within your mouth, not a widespread brain disorder.
