I've been feeling weird for the last couple of days, exhausted with a digestive system that seems to have come into contact with a scouring pad. I do suffer from extreme exhaustion and IBS, but it doesn't feel like this normally and I had been feeling a lot better for the last couple of months. This morning I have had strong palpitations and a spontaneous nosebleed. My husband took my blood pressure and it is measuring low, but not dangerously low. I normally have readings in the ideal range, though it was a bit high when I had a hospital visit 3 weeks ago. Am I having a reaction to Tibolone which I have been taking for the last 10 days? From the info I have read these are not recognised side affects.
