<s>[INST] hi doctor. my dad who is aged about 56 years got herpes on chest. he is having sever pain. he visited doctor and got some medicines. From websites in found that rubbing ice cubs will reduce the pain. I suggested him to do that but the pain has aggravated. Is it so dangerous? Should he be alone or he can mingle with people? Is there any home treatment to get it cured? [/INST] Hello, Herpes Zoster can be a very painful condition. If you let me know your dads medicines, I could suggest some that would bring him relief. It is normally not dangerous unless your father is immunocompromised due to other diseases. It can infect people who have not had chicken pox through very close contact. We do not normally isolate people. Some people advice honey, need, coriander etc. Being a viral disease, in most cases it will get cured with or without home remedies, but there are modern medicines like Acyclovir which can accelerate the healing. You are welcome to contact me if you have any further queries. </s>
