MMJ Spots

I sprained my neck due to prolonged hyperflexion (bending my head down for long periods of time playing guitar) over two weeks ago and my throat has been almost consistently mildly dry since that time. My neck still aches, possibly straining ligaments as well as muscles, and my only other symptoms are mild headaches at the back of my head and the dry throat. Some days it’s not so bad, but late at night it seems to get worse. Drinking liquid makes it feel better so the “dry spot” probably isn’t in the trachea but feels like it’s somewhere around or just below my Adam’s Apple, so somewhere in my esophagus I’m thinking. It doesn’t hurt to swallow or feel obstructed.
Maybe the neck swelling has put pressure on this area? Or pressure on the parotid gland?
Now, a small twist. I’ve been feeling some very slight maxillary and frontal sinus pressure on and off over the last week with the neck pain and headaches. I do not have any fever, swollen lymph nodes, pain in my teeth so if they are infected possibly viral. I could be wrong as the maxillary pressure may just be tense facial muscles and the frontal pressure could be a byproduct of the headaches but the frontal sinuses are tender to the touch. I was not aware of these symptoms when my throat first began to feel dry over two weeks ago.
Current Treatment:
I take 400mg Ibuprofen a day with food and use a heat wrap for my neck and headache symptoms. Things feel like they’re getting better but very slowly. Moving in my sleep is causing some flaring of pain within my neck that I notice when I wake up in the morning. I drink only water, milk, and grapefruit juice now and hardly anything sugary like soda for weeks. I see my PCP in 3 1/2 weeks and if I still have these symptoms then I will definitely see an ENT doctor for my dry throat.
History:
I have tested negative for HIV this month. Last and only chance of exposure over 5 months ago. I suppose it could be a singular oral papilloma/wart that coincidentally occurred with my sprained neck. The only way to know that is if it doesn’t clear up and I see an ENT who could schedule an upper endoscopy. This would really irk me as I only had one chance of exposure, again over 5 months ago. Could be GERD or Esophagitis though I don’t suffer all of the symptoms really. Some other possibly relevant history, I have Celiac’s Disease and have been on a GF diet for 4 years, and also quit smoking cigarettes and marijuana (after 6 years) for good and forever last month as well. I only drink 2-3 alcoholic drinks per week, if that, without any pain or side effects and coffee only a few times per week. I am not on any medications or use any other drugs.
