<s>[INST] My husband (69 years old) has had the Shingles rash for 10 days, started taking Valacyclovir HCL 1 gram every 8 hours for one week. The rash is on his bottom back and along the left side. This afternoon he now is swollen on the one side where the rash is (really swollen). Is this normal or what should we do? [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. I feel that it might be due to normal course of the disease. But I would advise you to go for Anti-inflammatory drugs along with Valacyclovir. Please do consult your Dermatologist and discuss treatment options. Hope I have answered your query. Let me know if I can assist you further. </s>
