Hi, this is my 22nd day of Shingles - I am having a pretty tough time and the last week or so I have been having to deal with nausea as well - thought tonight I would google nausea and shingles - happy to read that nausea is connected with shingles so in a way that is a relief! and its not something else I have to research - I dont as a rule go to doctors but the pain etc etc is really getting me down, I have acute pain in my left knee the same side as my shingles outbreak -  located at C3-5 across my back and under left arm - the knee problem came first probably about 4 weeks prior to the shingles - I was wondering if the 2 problems could be related? I am as a rule an extremely health and active 62yo woman.  Both the nausea and knee problem are causing me much unpleasantness, I would appreciate some advice. Judy from Australia - hesitant about giving credit card details - will seek advice from local doctor tomorrow - sorry.

Hello Judy, Welcome to Chat Doctor. The main cause of shingles is Herpes zoster, that's why I suggest-1. Start antiviral therapy, you can take acyclovir 500 mg 1 tablet 2 times 5 days/2. For nausea, you can use comparison 1 tablet 3 time after 1 hour before meal till relief.3. Use pain killers-nonsteroid analgesics and antiinflammated -diclofenac potassium 1 tablet twice a day during 5 days. Do not crush, chew, or break tablet. Swallow it whole, better after meal.4. Fexofenadin(Allegra) 1 tablet 1 time in bedtime for 10 days.5. Apply diclofenac gel to affected area, rub gently with massage. If it does not work then start to Chat Doctor.  Thanks, recovery soon. Best regards
