I am suffering from white discharge which is resulting in unexplained weight loss, pelvic pain, frequent urination, etc. I am 21 years old and want to become healthy, as from the age of 18 till today my weight is 42 kg, digits are not increasing. Also when I travel or stand for a long time my lower back starts to ache alot. This feeling is like my bones are melting or we can say, this is due to lack of calcium. Please suggest some medications.
