It doesn't hurt or ache and it's not pressure or palpitations. It's an odd sensation that makes me uncomfortable and feel unsteady. Kind of like butterflies but not in a good way. Doctors so far think it's just anxiety. But I feel like everything is blamed on anxiety. I don't know if it's coincidental but before my period and ovulation it is worse. I also feel really tired because I do not sleep well at night. I wake up a lot. I would say I have anxiety and depression but how can I rule out anything serious?
