My 80 year old mother had a choking fit two days ago, she had a lump of meat stuck in her throat, very little air was getting into her lungs, she went pale, lips went blue, this went on for approx 5 mins, we eventually got her to expel it, ambulance attended, but two days later she is coughing up blood, do we need to get her into hospital? She has had short breath since the choking.
