Having a really bad time of things. Woke up and was coughing again thought i saw blood, felt like i was going to pass out and still having pains in chest and arm. I had an ecg that was normal bloods done that were all normal and another chest x ray that was also normal chescked my urine and they again found nothing but the doctor said he was refering me to my gp so i can go to a respiratory clinic. I have come home and broke down i am so scared its horrible. I have a really bad feeling I have lung cancer. Not coping at all and more worried than ever.
