Hello Dr. Grief. I am experiencing a sharp dull pain on the bottom of my feet for the past few months. The pain is severely extreme, and sometimes I can barely walk on them. It hurts to put pressure on them when standing up or walking. I noticed a blueish black spot covering my entire bottom of my right foot just now. I am concerned if this is a circulatory or diabetic concern? Please help.My e-mail address is  YYYY@YYYY  Thank you,Kimberly
Hello, Thank you for using Chat Doctor. I read your question and understood your concern. The first and most frequent diagnosis is plantar fasciitis which need treatment with physiotherapy, shoe inserts, night splints, ibuprofen etc. The second option might be diabetic foot, and you can check the sugar levels in blood and urine to confirm or rule it out. Circulatory problems are even rarer, and you need ECHO Doppler ultrasound for that.
