Cannot diagnose: This needs to be seen to be effectively evaluated. Please see a doctor soon and hope this clears up. Congratulations on stopping smoking.

Oral symptoms: Please see your Primary Care Physician to evaluate your symptoms. They may or may not be related to your smoking cessation/malaria treatment. It will take considerably longer the 21 days for your body to heal from the insult of smoking, but your symptoms should be evaluated now.
