It depends why you were taking the
codeine. But, you could try an over-the-counter low dose paracetamol/
codeine and that should do the trick for the last couple of days. it will pass soon if it is just from the codeine alone. Stick with it, you're doing really well. Just hang in there. If you have an underlying reason for taking the pain relief, you need to see a general practitioner. It could be an infection that the codeine was masking.
