Should I Request an MRI Scan?

Hello, I'm a 20 year old male and have been experiencing dull aching headaches for a few month which can be in either side of my head and usually the back of an eye aches as well. They can get so bad it's disabling and all I can do is sleep, but even then it's extremely difficult, from what I've noticed; nothing specific causes them, they just happen on certain days at any time and can last for around 2 days if I sleep all day, being the 2nd day it usually lingers for a while. Lying down can cause a headache as well as when I lie down I feel an aching pressure on my head which is frustrating. I've been to see a doctor and they seem to think it's migraines without doing any sort of diagnosis other than just guessing.

Secondly, I've been having hearing problems for around one year, both ears feel constantly pressured and can sometimes randomly become severely itchy. I don't have any noticable hearing loss however, unless it's very minor. I've been to see a doctor about this and they checked my ears and don't see any issues but have referred me to a specialist for hearing tests.

Thirdly, in my mid teens, around sixteen or seventeen; I rapidly starting going shortsighted and then soon after I suddenly started notcing eye floaters and sparkles. I've also always had visual snow from what I can remember, which causes static-like vision when looking at dark areas but I actually thought it was normal/common for most of my life until I started seeing eye floaters and looked into these issues. I had tests done on my eyes and was told my eyes are perfectly healthy.


Also, take this into consideration when reviewing my story; I'm always fatigued, I do eat really poorly and don't go outside much but have had my blood pressure took and it's apparently fine, I've had also had a blood test around one year ago and it was fine apart from being low on a few vitamins.

My question is from what I've told you, do you think these could be all linked or seperate issues and should I push for an MRI scan or any other medical procedure?
