[|Human|] Hi Dr.... I woke up yesterday with my lower back sore when I looked in the mirror i had a red mark like a cross... it feels like a carpet burn and I dont know how it got there... today it is still sore... i cant feel it when i touch it but it still is sore and reddish brown like a burn....
[|AI|]  Hellos per your description it seems that you have developed a pressure sore (or bed sore). It usually happens in chronic bedridden patients at the pressure sites like lower back, back of the heel, back of the scapula etc.my opinion would be 1. Please take care of the wound (regularly Chat Doctor.  2. Change posture frequently while you sleep. Avoid pressure over the wound site.3. You may use some antibiotics like Amoxyclav or Cephalosporin group, if the wound is infected.4. Lastly and most importantly, if you are diabetic, then please take care of your glycemic state. If the sore doesn't start healing then you should visit a surgeon (Plastic surgeon) for further evaluation and management. Thank you.
