What Could Be Causing My Daily Forehead Headaches Despite My History Of Migraines And Use Of Lexapro?

Hello, I get headaches across my forehead almost everyday. They don’t hurt bad but are very annoying and make me feel depressed. I do have a history of migraine already since I was a child. I don’t have any nausea, auras, or sensitivity to light. Also have no dizziness. What could be causing these tension headaches. I’m on lexapro for anxiety and depression.
