Confused about symtoms(symptoms), suspecting allergy?

I have experienced following:- Red throat for a few months, no pain but there is swelling on one side of the throat.  Sinus tachycardia (began in April when I noticed the redness in my throat), PACs/palpitations (more recently - a week or two), at the time it all started I had a cold but had noticed one side of my throat was red for a while but dismissed it because it didn't hurt.  Itching skin, itchy spots, blood spots under skin, itching eyes, itching on outside of my nose, soreness inside my nose, post nasal drip etc... When I had the cold I had pressure in my ear on one side, heavy sinuses, as the cold went I had a cough which lasted ages, tickly and productive - nasal mucous clear, as is from cough. Had a throat swab taken - result was negative for infection.  Itching tonsils, itching tongue, rapid weight loss, palps after eating, burping and reflux, coated tongue.

Had tests including FBC, Blood Cultures, Chest X Ray, ECG's, Serum levels, Urea and Electrolytes, ESR, EFGR, Thyroid function - I was told I had the "Full works" blood test wise.  

The red throat appeared in April with dilated blood vessels appearing in my mouth.

My question is:-  Can all of this be an allergic reaction, i.e. an airborne allergy?  Or is it a systemic fungal thing?  Would my blood levels have shown abnormalities if there was fungal systemic infection? There is more to this but the program won't allow more characters.

No, I was perfectly healthy apart from suspected CFS which I had after having a virus a couple of years ago, but I got over that.
