In so much pain. Waiting for my 2nd LEEP next month. Worried they're missing something, after mis-diagnosing my throat cancer 2 years ago

Ive been diagnosed with cinn 3 and  will have a second Leep on the 7th of May. I'm in so much pain in my right groin area and lower right back ,I've previously had Throat Cancer and I'm in remission. I was mis diagnosed with Throat cancer for 2 years ,I was told it was Tonsillitis,  so my main concern now is that they haven't correctly diagnosed Cervical cancer and as far as I'm concerned I have all the symptoms I'm so fatigued all the time no matter how much sleep I get. I'm very worried.
