Lip blister

The cold sore on my lip is severe, and even though I have been consistently applying the ointment I received from the hospital, it still hasn't healed.

My lips are also quite dry, so I have been using lip balm for a year, but I even developed blisters on my lips, and they are very painful.

Do I need to take medicine to get better?

After suffering for over two weeks and being discharged, I immediately developed lip blisters, which makes it difficult.

This opportunity makes me realize once again the importance of health.
