Do
ovarian cysts cause extreme fatigue? I have for
cysts. One of them is a complex cyst measuring 4cm. I have had them for at least a year and being treated with birth control. I get abdominal pain, back pain, pain on my thighs, bloating and nausea. However, what really affects my daily life is the fatigue. I am always very tired, I feel like everything aches and just want to sleep. I work but lack the energy to go through an entire day without feeling I need to sleep!
