Hello  Dear
I evaluated your query in depth .
* The pain you narrated is related to herpatic 
neuralgia .
   It is not related to 
kidney stone / liver / medicines for 
cholesterol .
* This pain is among notorious ones difficult to handle , many times it goes 
   within days certain cases require months .
@ Have patience, continue medicines for 
Shingles ( anti viral drugs are the  
    corner stone of management ) , pain killers according to your doctor `s  
    advise 
@ Local application of 
Calamine lotion helps to give soothing effects for skin
    eruptions .
Hope this will help you definitely.
Feel free to ask any further health related query in future anytime .
Thanks for using health care magic .
Regards dear .
