I was told by my physician that the muscles surrounding my glabellar lines are extremely strong. My first dose in this area was 110 units. I reveived approximately 300U total over 6 months. Approximately 7 days after the last injection, I had a recurrence of symptoms of POTS with severe tachycardia orthostatic hypotension, generalized weakness, and dizziness after 6 years of being symptom free. Could this have been related to Botox?
