Capt,
Thanks for the post.
Wow, I can't say I've heard of this one before. Typically the tissue planes that the blood follows from a hematoma in the groin area are superficial. While they can cause a great deal of pain and discomfort and look absolutely horrible -- most resolve on hteir own. If I heard of your symptoms, I would probably refer you to a urologist to help me define the problem. I would also want to know from the patient so I would discuss your problem with your physician,
Remember, you've gone through a serious illness and a major surgery. This is still a sequlae of that and not something to be embarrassed about.
good luck
NEVER be ashamed to tell anything medical to a doctor, they have seen and heard it all and your problem is truley medical and related to a procedure, and might very well be a common complication that can be treated if caught early enough.
