 [ Symptoms ] recent erectile dysfunction should i avoid changing medication and go for a pump [ Disease ] hi dr and welcome to questiondoctors com it is rarely developing cancer this way even if it is sudden onset it would be due to an inflammation or infection that is not known yet or further symptomless you should start by using a strong antibiotic like augmentin for at least 5 days…if the node did not subside then you should go for us and later biopsy if only needed… speedy recovery wishes
