For me Natural herbs worked the best. Please don't be disheartened. Don't give up on yourself. I was suffering from the same for the last few years. I consulted the doctors about the same and took every kind of Medication, But sadly I never got the desired result. In my case a friend of mine suggested to use Hypericum Mysorense which is a herb that comes under Homeopathy. To be honest it all sounded fishy to me, Still I did all my research about this herb on the Internet to gather all the available information. Surprisingly everything I read about this had a Positive impact on the health of its users. I've been using this treatment from the past 4 months, and I can see that I have a better Immune system and I have not received any Outbreak after that. I would suggest you to give this Herb a try because trust me it Gives you the desired results and treats you!
