Hi, my mom have been suffering of severe dizziness (vertigo like symptoms) on and off but been worst for the past 2 weeks. She's on 3 medications. Please help me identify if combination of those meds are the cause. She's on 1. High blood pressure pills (Telmisartan I believe) 2. Citalopram (20mg) 3. Synthroid (0.15mg). Thank you in advance.
