Pressure on right side of head - has lasted a week

Hi I am a 20 year old female (soon to be 21) and I have been having this pressure on only the right side of my head only and it feels like my head is heavy on that side and my neck feels loose...I have no idea what is causing it and it is making me feel worried that something is wrong. The pressure only goes away completely if I press hard on my nose bridge and on a specific area on that side of my head...I have no other symptoms like seizures, dizziness (except once when I was tired), or falling over/losing balance, as well as vision changes or blurry vision, as well as headaches, which I only get occasionally. I'm just wondering if this is stress or anxiety related...and yes, I have a ton of health anxiety...I have been worrying from whether this was a result of a small stroke, brain aneyurism, or brain tumor. It could even be allergies although I have never had this symptom of allergies...I have a requested an appointment with my doctor to see if I can get this checked out just to ease my mind, but I do not want to spend more money on an MRI unless if it was free, obviously, because I had a tonsillectomy done back at the end of March and that is already costing us $2,000 about....I also have a bit of pressure on my nose on the right side too. I just wish it would go away and no medicines are helping either...I tried nasal spray, pain killers, nothing helped. It just feels like my head is very on the right side only and when I shake my head (I have tics as a result of Tourette Syndrome) I feel the pressure...I also don't have numbness either. Please help anyone! Thank you

I have never had a migraine in my life and I have had sinus infections before but only when I have been sick...this could possibly be allergies but I am not quite sure....it may even just go away on its own. I have scheduled a doctor appointment for tomorrow to talk about the pressure and see what she can do about it. I bet it will go away on its own...I just haven't had this sensation before...it initially started when I had a small sharp headache on my right side of my temple and I got so worried about it I made myself feel sick and that's when the pressure started developing so the likelihood that it could be just anxiety and stress related is very high.
