Hi rejennerate and thanks for your post. Triggers affect all people differently. What is a trigger for one patient might not affect another patient at all! As well, recovery times from flare ups vary from patient to patient too. Some seem to be able to bounce back naturally while others require medication. Since the symptoms you describe (chest hurting, coughing and not feeling well) have affected you for more than 24-hours, you may want to reach out to your physician for an evaluation. Please do check back and let us know how you're doing. All the best, Leon (site moderator)
