I'm in my twenties with the foll. symptoms:
1. irregular periods,
2. excess facial & body hair (legs, arms, hands, upper lip/chin, side burns, & practically the entire forehead),
3. cystic acne,
4. hair loss,
5. easy weight gain
6. skin hyperpigmentation in upper lip/chin (controlled with topical creams)
-I have had these symptoms for the last 4 yrs, a gynec. prescribed yasmin & symptoms 1 & 3 became normal.

7. feeling hot (it is like a temperature when u have the flu, lasts a few hours & then disappears).
8. slight/moderate ache in my fingers, toes, hands, legs (sometimes the muscles twitch or tingle, sometimes it hurts to type or do other things. don't know if it arthritic type of pain, but is bearable for the most part)
9. depression & mood swings
- I have had these for at least 2 yrs now (I don't know if it is the yasmin or something else)

Due to recent acne flare up & scant periods, I went to the gynec again who ordered an MRI and blood test. Now he has diagnosed me with pituitary tumor (prolactin 257). I don't have diabetes or thyroid. He also thinks I have PCOS although I don't know why he did not recommend any bloodwork or give me any medication. There is no history of tumor or PCOS in my family.

My question is: do I have PCOS? or are these symptoms due to the tumor? is it possible to have both pcos & p. tumor at the same time?

Pleeeeeeez help! I'm desperate to have answers. thank u very much!
