I think I have pulsatile tinnitus. I've been feverishly looking it up this morning. I woke up suddenly to this thumping in my left ear. The way I described it to my husband was a "constant drumming in my ear". It is annoying as heck. I haven't had a chance to have a doctor look at it because it's only 5:30AM in the morning right now. 

I started out googling on my phone "drumming in my left ear" and to my surprise, a lot of people have it and it was comforting but discomforting too as that they say there is no way to get rid of it. Some people have had it for years. The best description for what I have is "morse code thumping" because there is no rhythm. Sometimes it thumps really fast followed by slow thumps in between. I think people will think I'm insane if I tell them I hear morse code in my left ear. 

It says it's causes by a sudden change of blood flow or something is rewired in the brain. If it is the latter, is it going to make me more intelligent? 

All of a sudden, I have this desire to learn morse code. Maybe my brain is trying to send me a message or give me the next lottery ticket numbers. So I went to learnmorsecode.com and found this guide. To save you time, you can quickly learn morse code and figure what your thumping is your ear is telling you. See quick Morse Code guide below. Let's turn this special super power to our benefit. Jokes aside, I am going to find a doctor to take a look at my problem soon! 

LEARN MORSE CODE in one minute !

This is a code listening tool. Print it on your printer.
Place your pencil where it says START and listen to morse code.
Move down and to the right every time you hear a DIT (a dot).
Move down and to the left every time you hear a DAH (a dash).
Here's an example: You hear DAH DIT DIT which is a dash then dot then dot.
You start at START and hear a DAH then move down and left to the T and then you hear a DIT so you move down and RIGHT to the N and then you hear another DIT so you move DOWN and RIGHT again and land on the D
You then write down the letter D on your code copy paper and jump back to START waiting for your next letter. 
The key to learning the code is hearing it and comprehending it while you hear it.
The only way to get there is to practice 10 minutes a day. 
Listen to code tapes or computer practice code while tracing out this chart and you will find yourself writing down the letters in no time at all without the aid of the chart. 
The chart brings repetition together with recognition, which you don't get from any other type of code practice aid.
