I have been having really bizarre symptoms for 3 months: tight muscles, tight breathing, stomach not working properly (seems to have slowed right down resulting in pretty bad constipation). I started taking sertraline at 50mg and my breathing got bad and my tummy felt odd, really tight and as if my skin is too tight for my body. These have not gone away 3 months later. Could this be damage from the sertraline (i only took it for 2 weeks due to these side effects, stopped taking it 3 months ago). Im worried it may be permanent. Thanks v much
