First, sorry for the long post, but I want to give you all information i've received on my situation. I too had a vasectomy recently (on 12/18/2003). The procedure went fine, but 2 weeks after that, I had excruciating pain in my scrotum area. I saw the doctor that day and he thought it might be infection. I took 3 weeks worth of antibiotics for 2 different types of infection. As I expected, they did not help at all. I always felt that I didn't have an infection. My pain is mostly on the right side (a constant pain). There is a mass inside the scrotum that swells sometimes. My urologist finally said that it might be a sperm granuloma. Now, he doesn't know what else to do for me and tells me to just give it time. I've researched stuff everyday as to what my problem might be. I'm thinking sperm granuloma, spermatocele, or congestion in the epididymus. I have a small amount of pain in my left testicle, but it doesn't hurt unless I touch it. Anyway, i'm now wearing an athletic supporter 24/7. It has tremendously helped me when i'm walking. At least now, I can walk a little more normal. I've also started taking 600mg of ibuprofen 3 times a day. I just started that so I don't know if it'll help yet. Although, i've emailed some guys and 1 doctor about my problem. Each of those who replied said to take ibuprofen. The only guy whose pain has subsided mentioned acupuncture as well. His pain finally went away 1 year post-vas. I'm positive now and hopeful that my pain will eventually go away. It has caused strain on the sex life, but so far, we're managing. I'm surprised you've already had another surgery for the hydrocele, but I think if my doctor diagnosed me with something, I would have been more than happy for him to go back in there and fix it. I was constantly wanting someone to diagnose me with something so I can focus on that. For now, i'm focusing in the sperm granuloma. That's why i'm taking the ibuprofen (anti-inflammatory). I also found out that antibiotics would cause the ibuprofen to not work like it's supposed to, so i'm glad i'm off those now. From researching problems that a vasectomy might cause:
1) hydrocele - fluid that forms around the entire testicle. I don't think I have that because my pain is at the top of the testicle except after ejaculation, then both my testicles feel bruised (especially the back of each testicle) and are very tender to the touch.
2) spermatocele - fluid containing sperm that forms at the head of the epididymus (top of testicle). This mainly forms on the left testicle, but can happen on the right as well. I researched this quite a bit, and this could still be a possibility of what my problem is. Since it says the problem is at the head of the epididymus, I thought it might be, but since it says it mostly occurs on the left side, I don't know about it.
3) sperm granuloma - leakage of sperm from either the epididymus or the vas deferens that causes scar tissue to form since your immune system attacks it. Your body, of course, doesn't know what sperm is so it'll attack it. This is a huge possibility as to what my problem is. I wasn't told how long to wait to have sex after the vasectomy. I waited only 2 or 3 days when I should have waited at least a week. My pain didn't show up for 2 weeks, but still, sex early might be a good cause as to my pain. For this, you can either have it surgically removed, or wait it out by taking anti-inflammatories (such as ibuprofen).
4) congestion of the epididymus - from what I understand this could be caused by a number of factors, but mostly due to sperm buildup with nowhere to go. I thought this was my problem at first, and it still could be, but like I said, i'm focusing on sperm granuloma.
I'm guessing since you had your hydrocele removed, then your doctor was sure that that's what your pain was from. Also, I guess he/she would be able to tell if something else was in there when he/she operated on that.
Do you remember where your pain was exactly within the scrotum?
Does it hurt more or less after ejaculation?
What have you taken for pain?
Have your symptoms changed any since you posted?
I too wanted to look into getting a lawyer, but I don't think i'd have a case unless I could prove the doctor did something wrong (although, there is a vas that goes up to the op site and it seems stuck there). I've tried to get in to see another doctor, but it seems like they don't want to see me.
Good luck!
