I'm curious as to what should i do about these on and off allergies?

See an allergist: Allergy symptoms can be intermittent/episodic, seasonal or year round (perennial). An allergist can assist in determining what the allergic trigger is so that it can be avoided. If avoidance is not practical, then a plan for medication use or possibly allergy injections may be options. No need to guess--an allergist can help.
