Found a lump in the inguinal area of the lymph nodes which has been there for few weeks, it’s a hard painless lump but still feels like skin it doesn’t move and it’s about the size of a penny, I have shortness of breath- heart rate is constantly above 100, I have an extremely itchy area of skin for months, I’m in process of registering to gp atm so cannot make an appointment yet to get it checked. Does it seem like lymphoma from symptoms?
