Hi. Such type of pain in the back, right lower abdomen and enlarged lymph nodes in the groin can be due to infection speed to the underrate of the skin or due to muscle spasm. Your tests are normal. I would advise you to be seen by a Surgeon to have a physical examination. This is important part of the diagnosis as there are many diseases which can be diagnosed by clinical examination and a few more tests are to be done if ordered by your Surgeon. Till then, you can take Ibuprofen or so in therapeutic dosage, take rest, do hot fomentation.
