Well first off, my situation starts off with a somewhat chronic headache. It doesn't at all feel severe or sharp by any means, but more of a sinus pressure. After a couple days it made me worry so I began researching. After researching what might have been the potential causes, I noticed that a nasal decongestant that I had been using for sometime may have been the cause, afrin. I failed to realize the maximum usage, and I feel I may have overdosed past the 3-5 days recommended. Do you think an overdose of a nasal decongestant such as afrin is enough for me to seek emergency medical attention or is it something that if I were to throw away the afrin, things would sort of reverse itself and become normal?
