PCS can cause certain sensations to change. You may become more sensitive to certain smells or tastes and less sensitive to other smells or tastes.

At Brain Injury Support Group last night, there were three people with decreased or no sense of smell.

If anyone has a "sudden" change in smell or taste or other senses, it would be worth calling a doctor to be seen. If is is combined with any other loss of function or motor control, get to the Emergency right away.

mouse1, It sounds like you may have lost that smell sense but not realized it until the spraying started.

My best to you all.
