please realize that the internet poses some significant barriers when it comes to making patient-specific comments. as you know we can't see your knot or examine it let alone take a detailed medical history or do any diagnostic tests (if indicated). not knowing the true nature of this "knot" based solely on your vague description your question cannot be answered. you would need to physically see a medical provider and have this knot examined.
