Hello doctor,

I am a 22 year old male, who weighs 90 kg and 6 feet tall. I have pain in my chest and dyspnea from the past four months. For the last ten days, I noticed black and red patches in my mouth. I use tobacco, so I am scared that I have cancer. The spots are present on both side in my mouth and are paining. My cheek muscles pain and contract sometimes. I have increased appetite. My mouth feels dry, and I have a bump on the back of my head. My exams are going on, so please help me. I consulted a doctor for my chest pain and dyspnea, four months back. Tests showed that my vitamin B12 was 54 pg/mL.

Hi,

Welcome to icliniq.com.

  • The red and black patches which are painful are mostly oral ulcers. The blackish color should be the effect of the smoking habit.
  • With the history you have given, I suspect it to be nicotine stomatitis, which is ulcers due to smoking.
  • Vitamin B12 deficiency and stress are again a major cause of mouth ulcers. Please do not panic relating it to oral cancer.
  • You will be fine once you take vitamin supplements in the form of tablets or food. I recommend you eat a lot of green leafy vegetables like spinach and nuts rich in vitamin B12.
  • Smoking will cause obvious dryness of the mouth, so please drink plenty of water and stay hydrated.
  • For pain relief, apply Dentogel (Benzalkonium chloride) 15 g thrice daily with clean fingers and massage for 2 to 3 minutes and wash off with normal water.
  • Also, please quit smoking slowly. It will help you stay away from a lot of oral diseases.
