Rumbling in Ears?

So I've not been on here for a while because everything was going great!

Just yesterday at like 4 am I woke up with this weird rumbling noise and sometimes I get like muffled bass sounds like if a car is playing music with a heavy bass but the sound is VERY soft.

The rumbling almost sounds like shivering in my ears and they feel heavy or full. I'm not sure what this is and it's very scary and I haven't been able to eat and barely got anymore sleep after I woke up from it.

Now my anxiety is at 100% and I can't seem to get it off my mind. It also feels not just like a sounds but it almost is as if my ear is actually rumbling like moving or something but in the ever so slightest way.

Has anyone had this? Does it go away? I have been dieting and workout out very strictly and hardcore recently but I'm not sure if it's because of that? HELP ):

 

You may want to google search on MES or Musical Ear Syndrome as it can produce rumbling sound in ears.
