I've been mirtazapine free for about 7weeks now and I'm struggling to work out if I've hurt my back, have a symptom of anxiety or its a withdrawal symptom...mentally; I'm fab, back to pretty much normal but this aching and pain is really irritating me. I've been docs and he's honestly not too sure. I've booked an osteopath appointment as it is possibly its just a strain of lifting my huge 3year old son and sitting at the desk in the office but even painkillers aren't really easing it up. Its like a dull ache in my shoulder blades, arms and legs. Feels like sciatica but doc said it isn't that.
