Intense tingling on right side after my stroke . It had lessoned somwhat but has increased in intensity, I have progressed from a walker to a cane and when the house to no cane. Last week I was able to walk for 30 minutes outside and was very comfortable doing so. Yesterday my rt. side was tingling more when I walked the same course I had poor balance and stamina.. What could cause this? Is this normal or should I be concerned that something is changing?
