Woke up yesterday morning in agony - all down one side of my lower back. Was so bad I had nausea, was clammy and sweating. For a little while I genuinely thought I might be going into premature labour (am 25 weeks). I wore a heat pad all day yesterday, lay down for most of the afternoon and it had eased off when I went o bed. This morning I was a bit stiff but ok. Then I did the washing up and after standing in one position for 20 mins it had seized up again and the pain was back . Am going to spend the weekend resting and have got a wedge pillow that seems to help. Any other tips? Please???
