Swollen tongue and tight neck

In the last several years or so, I have been taking anti-depressants such a lexapro. Then for a while, I tried Effexor and though I felt better, I noticed my tongue swelling and cramping up while I talk preventing me from speaking with fluidity. It's almost like a stutter. I am an attorney and can't have this speech problem. I have tried going off of the meds but the symptoms seemed to remain for the most part.

It seems like the swelling and tightness is in my tongue, lips, jaw and neck. Any ideas on what might be causing this and if there is a cure?

Thanks,
