Pain on the right side of neck 2 in below jaw line don't hurt 2 swallow only wen eatin or drinkin can see pulse fast. Thyroid test r normal what is it?

Personally: I don't mind & I actually use abbreviations. But I wish you would take a little more care & use proper grammar/English asking your question.

Possible x-ray = esophagram & done with a physical therapist to study your swallowing mechanics. HRS, M.D., FACC ...Read more

My thyroid test showes 0.64 not 64?

My thyroid test showes 0.64 not 64?

TSH? Probably fine.: I'm assuming the "thyroid test" you're referring to is "thyroid stimulating hormone" or tsh. This is one of the most commonly measured thyroid-related tests.

The normal range depends on your lab and varies; but it's about 0.4 to 4.0.

So a value of 0.64 in that case is good - if it was 64, then i'd worry! ...Read more

When your thyroid test low how low is bad?

Not really bad.: The TSH level is just a test. There is no number that is really bad and all numbers can be fixed. There is a continuum of disease from mild to very symptomatic and some people may have a lot of symptoms despite relatively normal numbers. Best thing is to look at how you feel. If you feel fine then the numbers are good enough. ...Read more
