My wife, age 38, has been having a variety of symptoms: constant headaches, cramping, complete loss of sexual appetite & a tingling sensation in both breasts she describes as a ice cold burning that goes to her lungs & sometimes back. This "burning" feeling is not so much painful as it is mainly just very uncomfortable. She thinks it is a hormonal inbalance, & I don't have a clue?
Your wife should really see her gp to find out whats wrong, but to me it sounds a bit like the start of the menopause, I know she is very young but my mother had these symptoms and she was a lot younger than your wife and it turned out to be the beginning of the menopause. The doctor could confirm or dismiss this with a simple blood test. Hope everything turns out okay
