Swollen Lymph Node in Groin

[ArlosMom]

 My son is 3 year's old. 9 months ago I noticed his lymph node swelling in his left inguinal groin. There was substantial bruising around his lymph node. He did not get injured. He has no skin infection or athletes foot. He's perfectly healthy otherwise. I took him to the doctor and they immediately did a blood test. It came back normal (he had high LDH but everything else was normal). He had an ultrasound and found a small cyst in his spleen and a small unexplained cm mass in his butt that they weren't concerned about. They gave us antibiotics. The lymph node went down after a month and I moved on... however a couple months later it swelled up again and large amount a bruising again.... the doctor said it had to be a skin condition but his skin looks great, there's nothing on his skin except for the bruising near the swollen inguinal lymph node. My son looks and acts healthy. Now we're 9 months later with this unexplained swollen groin lymph node in my 3 year old.... I decided to sign up on this website to find out if anyone has had experience with this? I don't know if it's cancer because he doesn't have any other symptoms... but its so unusual and there's nothing on Google. On Google it states that a groin lymph node swells up if you have an STD, Athletes foot or Cancer. I know my 3 year doesn't have the first 2 but I can't rule out cancer yet. Any experience from someone who has had a Goin Inguinal Lymph node flair up would be helpful to me. Much love to you all ❤️ Thank you so much.

Hi,

Sorry,  I don't have anything helpful to add. I just wanted to check and see if you've had any answers yet.
