Hi, I'm new here.

lately I've been having pains in my chest and right leg as well as testicle, and also have a little lump in my neck. I've spoken to my GP and got bloods done and they all came back good. I also went to a sexual clinic and I don't have any STI or anything that could cause testicular pain. They suspect it's a cyst. My mouth is constantly dry and my whole neck and throat feels full and I'm worried to death I've got a cancer that has spread throughout my body. I've also had blood at end of my stools but the GP has been very dismissive and said it's all normal and only organised a further blood test, saying everything feels normal, but I don't feel well at all. I'm only 20 so it's very scary that my life might be cut short, I've got so many things planned but I've not been able to do anything for past few weeks because I'm worried sick that it's something sinister and my GP is ignoring my worries. I know if it was a cancer that has spread badly there would be signs in my blood tests, but nevertheless some people have been diagnosed with it with normal blood tests. I'm getting desperate to find help and make sure it's nothing bad but I can't see to find anywhere to go, and it's mentally draining me every single day :( any help would be greatly appreciated
