mrsmith,

Welcome to NeuroTalk.

Resuming your studies increases the stress load on your brain. This can cause a return of symptoms. You should try to return to studies at a slower measured pace.

The shampoo experience can have two problems. The shaking of the head and neck can be stressful on the brain. You need to communicate a need for a more gentle shampoo. The neck, especially the upper neck, can be traumatized by the shampoo bowl. The way the neck is supported by the bowl can cause the blood flow to be impeded, it can cause a strain on the ligaments that connect the C-1 (atlas) to the occiput (base of the skull). There is a condition known as shampoo sink embolism that is caused by the trauma to the vertebral artery loosening arterial plaques. I doubt this is a problem for you but it does demonstrate how a shampoo sink can be traumatic.

There is no way to tell what caused you return of symptoms. It could be both.

Please tell us more about the symptoms that have returned. There are many here who have been through this same experience.
