I have been feeling sick lately, with more and more symptoms showing themselves. After googling my symptoms I learned that I have almost all of the symptoms of a person with lymphoma. The only symptom that I can say I don't have is weight loss. I am not jumping to the conclusion that I have lymphoma, but I would like to know what type of doctor I should go to in order to receive tests that will tell me what is happening with my health. Do I need a blood test?
