What Could Linguinal Lymph Nodes Suggest?

Hello, I recently noticed that a linguinal lymph node on the right side was about the size of a pea. It didn t hurt, but it worried me. So I called my doctor and got it looked at, and he put me on a medicine to help reduce the size, and told me that if it didn t disappear within two weeks, to come back in for further evaluation. This was 5 days ago. Since that time, I ve experienced it hurting some when I touch it, but now that I quit touching it, the past two days, my right leg feels weird... it s like it s numb or something. Sometimes it hurts in the front pelvic region, other times my calf hurts, and sometimes my right foot feels like it s falling asleep. I have no clue what is going on? Has anyone experienced anything like this? Thank you! - JC
