When I go to the gym, I only go 3 times a week, riding 20 min at a time and I hardly ever ride the bike at home. I just did it that one day because my orthopedic doctor told me not to do any weight bearing exercise because of a problem with my knee and I accidentally overdid it. I have been sitting a lot because of the bulging discs in my back, but the pain was there before that. This is the MRI done on May 20, 2009 on my knee. I don't know if this problem could be related. An EMG was performed on April 12 by his clinic because he thought the 2 might be related. I just happened to see my orthopedic doctor today right before I saw him, I asked for the MRI to give to the neurosurgeon. When I tried to show him the MRI, he said he doesn't read them. He was very uncommunicative and distant. This was only the 2nd time I've seen him. I asked him about the nerve compression around the L4-L5 area and he said couldn't do anything for me surgically. Here is what the MRI on my knee showed and my remaining questions.

1. Do you think the 2 might be related?

2. Does nerve compression heal itself? If he won't do anything surgically, what can I do for it?

3. I did have a fall when I was delirious because my family left me and I wandered around and I know I fell because I had a big gash on the back of my head. They did a CT scan of my head in the hospital and nothing was found there. I noticed on that website you gave me, it said it could be caused by a fall on the coccyx. Is it possible I have that and not know it? What tests are done for that and is there a solution to it? Would something like that have shown up on the meylogram? He never even suggested anything like that. Like I said, he was uncommunicative and distant, so I don't know if it occured to him. It's the first I've ever heard of it.

4. What is sacro-spinal fixation? Also, I have an overactive bladder which I take medication for. Could any of this be connected?

5th and final question. What kind of doctor should I go to to resolve all of this?

Impression of my left knee:

Bone bruise again seen involving the lateral patellar facet with cartilaginous loss about the lateral aspect of the joint. There is a moderate knee effusion with edema posterior to the knee joint space in the proximal calf muscalature likely a repruted Baker cyst. Other etiologies not entirely excludible. Bowed medial collateral ligament suggesting strain. Bone bruises as described above including the posterior insertion of the posterior cruciate ligament and posterior tibial plateau and the fibular head. Strain in the popliteus muscle also can be excluded.

I was asking if lasix can have anything to do with the crotch pain.

Can nerve compression around the L4-L5 cause pain in the crotch area by way of a peripheral nerve? The neurosurgeon did an EMG test. I'm assuming he concluded that there was no link between the knee and the back, so I'm discounting that.

My physical said that nerves grow .25 millimeters a month. Does nerve inflammation have a specific time frame like to heal, also?

How is nerve irritation around the coccyx diagnosed? What kind of test would it show up on? X-ray, MRI, or meylogram?

Thanks.
