I have not had any myself, so I am not really sure what they feel like. Both my sister and my mother have. My mother used to find them every year, she would have them aspirated (the fluid gets removed) and all would be well. One doctor told her to lower her caffeine intake. She did and has not had once since. My sister, who is not as big on top as my mother, had them removed. I am not sure if she has had any since then.
I agree with Mal. Don't miss that appointment. I wish you lots of luck and will be thinking about you.
