Anyone know if roids worsen the condition of allergies? I'm pretty sure I have allergies because I constantly have a runny nose and cough alot. I'm currently taking Allegra and running a cycle. I've had this cough now for exactly one month and now it's starting to become very annoying. I started my cycle about one month ago also so I don't know if it's directly related to the cycle or if it's just allergy season. Another possibility that I could have "whooping cough" which is a cough that last a few months. Anyone have any ideas?
