Hi. This is most likely due to something going on with your inner ear. you could have an ear infection or virus that is causing inflammation in your ear and these symptoms are indicative of vertigo caused by that.
Talk to your mom about seeing a doctor. good luck
Let me rephrase that. COULD be indicative of an ear infection or virus. This is not a replacement for a doctor so you should be seen for any type of diagnosis. good luck
Tell your parent and ask them to book you in to see the doctor urgently.
Because you lost vision, your hearing, felt dizzy and lost some feelings in your arms is not an indication of a straight forward ear infection.
I trust your shower water was not too hot. It seems to me that there was lack of blood getting into the brain, due to either too low or too high blood pressure. This is one possibility, but there are other medical conditions that could cause the symptoms that you experienced, so it is very important that you see your doctor urgently.
Let me know how you get on.
