The Symptoms Are Whole Head Ache Including Tightening Of Facial

The symptoms are whole head ache including tightening of facial skin and lips, a sore throat and difficulty sleeping the night after contact with indoor geraniums, as well as a large poinsettia plant. Might this be an allergic reaction to one or other of these plants? Also inside the same home are a small variety of green leafy tropical plants. Thank you.
