Blessings to your husband. That is wonderful that he is feeling better in the leg. He has been through so much.
I had a microdiskectomy on L4/L5 for a compressed nerve 9 months ago and still have very sharp and frequent leg/foot and toe pain, but the leg pain did come down in intensity at 6 mons post op and i suddenly went from 20% strength in the leg to 50% overnight. Just prior to that, I went through two weeks of increased pain in the back/leg and then it stopped and my leg suddenly got stronger. Unfortunately, a month later, I got increased toe and foot pain, from level 8 to level 10. Ugh.
I too have researched this nerve damage issue and asked questions of the doctor, as I don't want to limp forever and can't continue in that kind of pain.
I was told the same thing that the nerve heals at about one inch a month or less. that most healing takes place the first year but continues for 3 years and even longer.
My PT said that Christopher Reeve proved that by getting on a recurabent bike (I guess one that moved his legs for him) and that blood supply through exercise did heal some of his nerves. Before that, they didn't know nerves could regenerate that much. Before he died, he was doing PT in the pool and I heard he was actually moving even more. My PT says water walking in the pool is the best thing you can do.
I was told by the doctor and PT that you need to provide blood supply to the nerve for it to heal (as in walk) and build up muscle (which also helps the nerve to heal). My PT said that even if a nerve is damaged it can create Other pathways (in other worRAB go around) and strengthen those so the signal gets through. She said that nerves are "unforgiving" and "slow to heal" and "you never know what they'll do or how they work exactly but the body finRAB a way to heal."
What else....oh...since my nerve pain has gone on so long and it increased, my doctor put me on Neurontin to get the nerve to stop being hyperactive. I was getting stabbing level 10 pain. I was concerned about taking a drug that would "slow" the nerve signals, as I read somewhere that the nerve neeRAB to send those signals to heal.
As I understand it (and I';m probably misguided as i got it off the web) the nerve keeps trying to send a signal across that damaged area and the signal builRAB up til it "stabs" you. So I told that to the PT last week and said, "Should I be on neurontin if it's slowing my nerve signal?" and she told me that they have found that nerves will get stuck in hyperactive mode and you need to break the cycle otherwise they can go on hyperactive like that indefinitely.
So she explained to me that they need to calm my nerve and break that cycle and that it will still heal. My doctor also said that stopping the hyperactivity in the nerve will help the nerve heal. I hope they are right...it's so hard to know what is correct...
Any one else chime in here????
the problem wiht this drug is it slows my brain as well...but it has taken away 95% of the leg/foot pain and I can stand longer and walk easier. Prior to that my doctor had me take a percocet to ease the pain enough to take a walk.
I don't know if any of that helps, but it has taken me over three years to get that information. My doctor told me most of the time a person's nerve is only bruised and they are the ones who wake up and have no more pain. Others, like me, have a punctured nerve sheath which takes longer to heal. I was told i will need a full 3 years to recover. So there are different levels of nerve damage, and frankly, I think they figure out what level by watching you over time to see how you heal unless they can phsycially see the nerve.
So, I guess what I have learned is EXERCISE to within tolerance. I do so under the guidance of a PT so that I don't do further damage to my back. Like others on here, I have been close to giving up due to pain but the doctor keeps telling me to "hang in there" and "keep doing the therapy" and "keep walking one hour a day." He said he has seen severe cases much worse than my own who one day woke up with no more pain. Just like that. So he is very hopeful.
It's very hard to keep the "hope" when you are dragged down by pain and disability and don't see much progress over a long period of time. It's also hard to learn when to exercise and when to stop due to pain. I have found that continuing to walk once I've reached a level 6 pain in the leg/foot/toe will take me right to a level 9 if I don't stop and lay down, and then I'm down the rest of hte day. Or 4 days. So you walk a tightrope, learning to listen to your body which will tell you when to do what.
I hope that helps someone out there. This is a good thread. What has anyone else heard about nerve regeneration?
