I recently came off lexapro (escitalopram) (slowly). 3 weeks later i have joint stiffness, swelling and pain in both knees. could lexapro (escitalopram) cause this?

Usually not: Those are the some side effects.Constipation; decreased sexual desire or ability; diarrhea; dizziness; drowsiness; dry mouth; headache; increased sweating; light-headedness when you stand or sit up; loss of appetite; nausea; stomach upset; tiredness; trouble sleeping.

Probably not: But pretty much any side effect is possible w/ any drug. However, having it happen 3 wks after stopping doesn't raise a lot of suspicion.
