Against my better judgement (and advice on this forum) I took Duclofenec (NSAID) when my arthritic hip became very painful and I couldn't walk. It worked very well but, after about a week on it I developed cramping and loose stools. I stopped taking it yesterday. Today the cramping/loose stools continue and I've noticed what I've heard described as 'coffee grinds' in the stool. My question - is there anything I need to do or just stay on the anti inflammatories and let it settle and heal? Thanks for sharing any experience or advice that you can.
