### input:
I recently had a pelvic exam when doc noted a sebaceous cyst about the size of a popcorn kernel. He poked a hole in it to let it drain. Two days later my left inguinal lymph nodes were swollen 5 times their size according to ct scan and i was in extreme pain and he lanced the small cyst and packed it. Took doxycicline and with some reduction the cyst healed completely. But left with bad pain in left groin, left lower vaginal perineum sit bone area which radiates into upper thigh and inner thigh. I explained and showed him and he put me on steroid pack. He said thats all he can do as this is not his area of expertise. This is the same doctor that gave me hysterectomy cestecele and rectocele repair 2006. (Also had a inguinal and femerol hernia repair in 1998) Anyway, I go to my family doctor and he said thats not his area of expertise he cant help me...but don t bother going to the emergency room because they wont help you either and my obgyn should have taken care of it (Obgyn already said nothing he can do) He wont look at anything below the underwear but does think I have diverticulitis due to extreme pain when he touched that area. He prescribed me cipro and thats all he can do. I do have pelvic pain above sigmoid colon and chronic diarrea. And last colonoscopy in 2012 revealed small diverticulum in sigmoid and removed 9 polyps (2 were precancerous). In the meantime here I am one month later after two antibiotics and steriod pack painfully sitting at computer searching for ideas to take an active part in repairing my quality of life. Where do I go. What could be wrong. Not that I think i have Leukemia, but my father did pass away from Lymposidec Leukemia. I wish you could help.

### output:

HI, thanks for using Chat Doctor The swollen lymph nodes would have occurred due to inflammatory response from the trauma (lancing the cyst) in the area and infection. It is possible that infection was introduced when the cyst was poked. It is possible that the inflammation from trauma and infection affected underlying tissue. There may have been abnormal healing. You may need to consult another gynecologist regarding the pain in the pelvic region. The pain in the coccyx (sit bone area that you mentioned) is termed coccydynia and may be treated by your GP or an orthopedic doctor. I hope this helps
