For the last couple of weeks my fingers have been swelling up, mostly just at night. My knuckles hurt and I'vce had to take my rings off because they were getting too tight. When I did take them off they almost got wedged on my knuckles which has never happened before. They aren't itchy or anything like that, but they do hurt when i wake up in the mornings. I've not been able to get an appointment with my midwife for 3 weeks, and she's booked up for this next week too. Is this normal, or should I book in with the doc?
