Possible pharmaceutical trigger of G. Herpes reccurences in infected individuals

I have recently realized that of the total of 5 reccurences of genital herpes reccurences I had during the last three years since being diagnosed, the last 3 reccurences were all immidiately preceeded by the ingestion of a certain type of anti-inflamatory painkiller. The last reccurence happened 3 days ago ( my last reccurence before this was 16 months) and it started 2 hours after I took the medication. I have not stated the name of the drug for obvious reason but if anyone suspects that this has happened to them please reply.  At the time I took the drug I was on holiday, had relatively no stress, had been in  good health and had plenty of sleep in the week precceding the attack.
