Everyone keeps saying It's just my sinuses, but...?

[MisterSky]

• Random headaches & head pains all around my head and sometimes even my neck
• Feeling of Having to put effort into breathing
• Severe ear pain which strikes at random
• Tingling all around head, neck, and face
• Neck tightness
• Neck spasms when sitting still and breathing (occurs at random)
• Randomly feeling sick, mostly in my head only
• Electric rush feeling in head when i move my eyes around
• odd throbbing sensation in my forehead and front of neck whenever i sit still and breathe

I'm at my odds end because it seems like i'm just being suggested allergen medication after allergen medication after and i'm not sure if this could even really be allergy related, i'm afraid it could be something completely different. I've tried Flonase, Sudafed PE, NeilMed Sinus Rinse, and now Claritin-D and all have done nothing for me, most cases they've made things worse. I have absolutely no idea what's going on and no one else seems to either. All this stuff is very hard to just ignore since i feel it constantly 24/7. It's been 21 days since this has all started and it's only progressed and gotten worse. Is there anything else that's possible to try or do that has a FOR SURE effectiveness? I honestly can't do anything with all this happening to me and I don't know how to fix it in the slightest or what's even going on. I'm absolutely miserable and am desperate for help with this.
