Freezer, I have the same dull ache in my head that you seem to be experiencing. I don't have the tingling but the ache, like yours, never leaves. I also get migraine headaches although they seem to be less frequent than the first two months.

As for the other symptoms after walking, yes I've had dizziness, nausea, increase in head pain, increase in blurry vision and feeling dazed - Now, when I was 3 weeks into my injury I experienced these symptoms everyday without walking and still do today although they have become weaker and less frequent (I am now going on 3 months). I have only tried a slow walk about 3 times because I was going nuts at home doing nothing. My doctor reminds me to only try something new when I am symptom free.

One day at a time...
