Suggest Treatment For Groin Pain After Inserting Mirena Coil

At the beginning of the year i was admitted with a suspected blood clot that travelled up my right leg and ended in my groin. i was put on a drip of heparin overnight and had a scan the following day and it showed up clear. i was discharged with no further treatment. i have recently had a mirena coil fitted and the pain in my groin has come back 10 fold. i have tried paracetamol, ibuprofen and diclofenac but nothing works. also i can not sleep on my right side because of the pain
