NC. DD 20 has clot on the right lung which was diagnosed 6 weeks and has been on thinners for. On Wednesday, she ended up back in a&e due to having chest pain that was in her upper back too . DR said bloods were fine and chest x ray was clear, but when listening to her heart he heard a systolic heart murmur. DR said it was probably new and she had her heart checked out numerous times when clot first came. He wrote to GP for them to investigate. She has a GP call Monday. However, tonight she says the pain is really bad again she has rang 111 and waiting for call back but should I just take her back to a&e. She said the pain is worse but hesitant to go back to a&e as unsure what they will find as on weds xray clear and blood tests fine.
