Grab feeling in chest for a few seconds then goes.

been on citalopram for 6 weeks now. felt great the 4th week now my panic attacks are back and i keep getting this grabing feeling in chest and it stops me from talking. It feels like it catchs my breath also. has anybody had this feeling before. It has totally set my panic attacks off again. Just keep thinking i have irregular heart beat. cheers

hi Sean
Yes it is all part of the side effects it does get easier so hang on in there x Do some breathing exercises also i downloaded an end anxiety app to listen to x
