Keep getting like the feeling of hair or cotton wool stuck at back of throat, i do also get and am prone to throat infections, currently on an antibiotic for one, what could this be, would it be part of throat, weird annoying sensation?

Throat discomfort: Unless a throat culture demonstrates presence of pathogenic bacteria like group A beta strep, taking antibiotics is not only futile but can cause side effects. I assume you're not a smoker. Excessively dry air,pollution,the common cold are some causes of minor throat discomfort. An Otolaryngologist can evaluate and advise you further.
