I have swollen glands and a sore throat after ultherapy, as well as nausea. Am I having side effects?

I doubt your symptoms are a result of your Ultherapy treatment. The heat energy from the Ultherapy procedure is not transmitted deep enough to damage the throat or lymph glands. You should make an appointment to see your primary care doctor who can examine you and treat your symptoms accordingly.

Swollen glands are not a side effect of Ultherapy. I recommend that you see your primary care physician. There may be inflammation after Ultherapy but I have never seen nor read that it causes lymphadenopathy. Read my Ultherapy ebook provided on the link below. 

What you're experiencing doesn't sound like side effects to Ultherapy. Although complications from the treatment are rare, they usually take the form of bruising, numbness, and tingling, not nausea and headaches like you're experiencing. I would recommend making an appointment with your doctor to see what's causing your symptoms.

These symptoms do not sounds like side effects of Ulthera. I recommend visiting your primary care physician to determine the cause. 

no, this is not from ulthera. go and see your primary care physician, they will do the necessary evaluation and treatment
