2-3 days before my period i am ill with sore throat and a cold? why is this and what can i do to improve my health?

Is this a pattern or: One time occurrence. If chronic - get medically evaluated. If one time then you can improve symptoms. Saltwater gargles are helpful. Mix a tsp of salt in 8 oz of warm water – gargle w this several times/day. You can gargle w aloe vera juice a couple of times per day. A mix of chamomile tea w honey ; a small amount of lemon juice is good.
