"i was diagnosed with pleurisy yesterday  - intense pain on inhalation/yawning/coughing etc - in fact anything that involved inflating the lungs felt like i was being stabbed in the side.  was prescribed dicloflex (diclofenac sodium in uk) in 3 x 50mg tablets  a day. didn&#039;t seem to make a lot of difference the first day, so i continued using paracetamol codeine for pain relief. today i&#039;ve been a lot more comfortable - it seems like it took three doses to get started. i was even able to yawn earlier and i spent a little time sleeping lying down this morning - both of which would&#039;ve been impossible yesterday."
