Hi all, I had an op. 13 years ago (I was only 17) for what, I was told at the time, was a sinus. I did not have a lump, or any discharge, just pain. This was in France, I saw a consultant and was operated and sutured the next day. I am now in the UK where it is a huge mission to get to see a specialist. The pain has come back 4 months ago. Still no discharge or lump. I ran to my GP and insisted to see a specialist asap as I was certain this was another sinus. The consultant had a quick look and booked me in for an op two months later. In the meantime, the pain continues (only when I am sitting), but things do not get worse. I went to hsp. this morning for my planned surgery and was told then by 3 different Drs that I should not have surgery as they do not believe this is a sinus. They believe this is scar tissue (13 yrs on!!??). Now, I read the whole website and I have a few questions for the people there, who know a lot about it: 1- Is it possible to have a sinus if there are no lumps, no pits to be seen and no discharge. I understand that sinuses can be very deep, but would there still be pits to be seen? Furthermore, if this was a sinus, would not it have evolved over the last four months? 2- I think that the symptoms correspond to coccydogynia... but would not that be a coincidence that I have had a sinus there before? Unless this was never one... 3 - Has anyone had a MRI scan before to diagnose? I did not want to leave the hospital untreated so insisted to get a diagnosis so they ve booked me for a mri which will supposidely show whether there is an infection. Many many thanks! I have just lost all faith in my Dr's ability to diagnose and am starting to completely panick over what this could be if this is not a sinus and if it IS one, over what it will take to go for surgery... Thanks again!
