I would go to the doctor!

I saw an article on DailyMail about that: Becki Conway left blind after suffering reaction to prescribed drug pairing | Daily Mail Online

"Initially after taking the pairing of the prescribed drugs, she began to feel better, but two weeks later she started feeling symptoms similar to those of the flu including a sore throat and a dry cough"

It took her 2 weeks before she got flu-like symptoms... just like you

It may be a coincidence or it may not! But that lady went blind in one eye, so I wouldn't risk it. I would go to the doctor immediately!
