T-man, after having ones's noggin opened up twice in one year, I don't think any of us would be what we used to be, but I think we are all very happy that Jr. is not only recovered, but RACING!!!
A few years back I had the misfortune of becoming the recipient of cluster headaches which if you have never experienced, leave you unable to function normally, and nothing you ever want to have.
After many tests and MRI's my neurologist looked at the data, precribed some pain medication, and had me come in every two weeks to check on my condition.
After about two month's I went in to see him and told him that they had dissapeared the week before.
He said " Then we are done unless they come back".
I asked him what had caused them and his answer was: "unfortunatley we cannot unscew the top of your head to look at any problems. We can see from a MRI if you have had a stroke or have cancer, but other than that we just treat the symptoms as we can only guess at what is causing the problem".
That was good enough for me.
