Hi, Male just turned 55. Train 4 days a week (every other) 45 min of stretching and core , 5-6 mile trot and 45-60 min in the gym with weights. About 6 mos ago I developed a persistant tingle/numbness in both thighs, soemtimes calves, that, even when I took a week to rest off didnt go away. They do seem to be warmer than the rest of body. Last night I noticed I was phazing out, that is 1-2 seconds of vertigo or dizzieness. Nothing prolonged. Noticed the write up on spinal stenosis but was also wondering about brain issues because of the phazing out. Since my wifes dad just had brain cancer and was without symptomology until one day when he just started mumbling, should I bring up a brain CT/MRI just in case?? What do ya think?? Thx, Bob
