I met with a neuro physical therapist before and then after my tap. I did not notice any difference how I felt. But now 3 days later I do feel a difference in my gait, and bladder control and foggy brain. Is it possible that it would take 3 days to feel like the tap helped? And also, can you have good and bad days with NPH? This is brand new for me. Don't know what to expect and what is in store for me. Any help would be so appreciated. Thanks
