Citalopram. Muscle and joint aches

Hi everyone.
just wanted to see what your experience of Citalopram has been. I’ve been on 20mg for 5 weeks now, and I’m getting knee aches in my knees and leg muscles. I’ve always been a bit creaky in the morning, but the tablets have made me feel worse.
is this a short term side effect that anyone else has?
I’ve got the usual tiredness and could sleep anywhere problems, but the aches are the worst.
thanks

Sounds like a blood flow issue.
