question: My 84 yrs. mother suffering by herpiese since 30 sept.2010. First of all so many blisters formed at left side of stomuck & back. By the consultation of Dr. we have given a course of Herprex Tab. and  locally applied Herprex cream for 8 days. Again Dr. started Tagrital tabs for 10 days. Now top skin is completly dried and became blackish, but very qute pain occuring inside the skin that is untolrable to her. You are requested to guide us how to prevent this.
