I have been experinecing tingling and numbness in my groin and inner left thigh. The tingling happens once at night while sleeping and as i change my posture, it goes away. I have pcos and havent had my periods for 2 months now. I was on medroxyprogesterone before that and had withdrawal bleeding but no actual period since then. I can feel my heartbeat in my lower pelvic area and abdomen. No pain in any part. I am overweight (bmi 28) and have recently started gym. I also feel a little lightheaded sometimes. What could be the reason of the above symptoms nd what should i do?
