Loestrin 24 Fe and 15 minutes

In December of 2006 i was taken from school to the emergency room for sever menstrual contractions. It was the first time i had ever experienced that kind of pain during my period. Literally it felt like i was going to have a baby.
My doctor put me on Loestrin and it worked beautifully. My periods stopped completely after 2 months. I had no symptoms at all, no side effects either. Now that i have been on it for almost 2 years my periods are coming back (only lasting about 3 days), my cramps are returning, ive developed muscle and joint pain, my lower back stiffens up making it difficult to stand or walk for more than 15 minutes, i get dizzy easily, and now ive developed brown spots on my back near my shoulders. if any one else has these spots please let me know so don't think im crazy. My doctor says i have a fungal infection but iv had it for 6months now. IDK!!
