Oh, sorry I included 'shoulders' in the title. I heard the word on the TV and accidentally typed it too.. hah, one of my bad habits.
Without examination,confirmation of a diagnosis is tough,but it can be due to hyperpigmentation of the skin. This darkening occurs when an excess of melanin, the brown pigment that produces normal skin color, forms deposits in the skin.
Treatment involves hydroquinone, azelaic acid, corticosteroids, tretinoin cream and laser treatment. Pls discuss these options with your dermatologist before using them.
Hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional queries.Warm regards.
I went to my doctor today and she thinks it is just irritation from sitting because I'm really skinny. She prescribed me to hydrocortisone, hopefully this will make it go away!
