Hi Dr Diana, I have dark spots on my gums that are turning darker brown and spreading. Yes on the sides of my elbows are darkend there’s a patch on the front of my lower leg/top ankle spreading down to the top of my right foot. The lines in the palms of my hands are dark brown and my knees. I noticed the spots on my gums over 8yrs ago but didn’t think anything about it now its almost all of my gums. I was started on cortef 10mg 2 wks ago. My energy has improved but my appetite is still in the dumps along with every muscle spasming in spots I never imagined could spasm. Also still feezing all the time… But I’m on my way to finally getting some answers along with the correct meds! 🙂 I know I have adrenal insufficincy I will find out in 2wks if its true Addison’s or not.. I will keep ya posted!! Thanks for your educational input I wouldn’t of got this far with out it;)
