hi I drink lots of coffee every day, I have been on HRT for 1 yea, been using Progynova 2mg once a day, last week I switched to Estrace 2mg, after a week and all of a sudden I woke up with severe Hives, itchiness, and I had to go to Urgent Care to get Steroid pills, I stopped taking Estrace 3 days ago but Hives still showing every time I drank coffee, please advise, I never had any problem earlier combining Progynova with coffee, thanks
