Five Swollen Inguinal Lymph Nodes

Hi,  I have 5 swollen inguinal (Groin) Lymph nodes, and had a series of tests CT scans Ultrasounds!  All blood tests are clear. This started May 2018 and went to the doctors straight away! I live in Cyprus and am an ex-pat! On the last Ultrasound the 2nd the man doing the Ultrasound said one looked like Lymphoma. He said it was matted and vascular 1.67cm and recommended a biopsy.It is hard and attached and just came up one day! I have been pushing since May 2018 and there is a language barrier as I don't seek Greek!  Finally they did a removal of the main hard Lymph node 1 weeks ago and awaiting test results, but can be up to 2 months they said! If I press on that region with the other Lymph nodes I feel very sick like I want to vomit!  What could this be,  and could it be a type of Cancer? As I cannot read the notes and only limited tests done and have to go private for smear tests mamogram and the first Ultrasound but have 5 swollen Lymph nodes from last May now 4?  Thank you
