I hear you & empathise with your friend's issues.
However, dermatology is a very visual line & as such, one needs to upload good clear digital images onto this website using the upload data icon to the right of your screen.
This condition may just be what we term 'morphea' going by your clinical description & if so, will require a skin biopsy
&/or intralesional injections & will require the services of a dermatologist
on the ground near you.
Is there any other significant medical history in her life or a similar history in any of her family members? Are there a lot of stressors in her life & is she on any medication?
Good luck & heres wishing you good health
