Hi, I have a fluid type lump on the end of my testicle and im sure iv ha it for years but anyway i went to see the gp and he said yes its definatly cyst like, He said cancerous lumps form on the testicle and hes confident its a cyst but hes sent me for an ultra sound to be 100% sure. Since then iv felt so ill, Iv had this flu like symptoms for a week and cant stop thinking i have cancer and its spread! I have the ultra sound on tuesday and im fearing the worst. I can hear a rattling sound on my chest when i breath and it does feel like a common cold but sometimes during the day it just dissapears and its like i dont have a cold?? Then bang its there again. I also have dull aches in my testicles, low abdomen and upper abdomen. Im so scared im feeling much worse and very sick :-(
