Hello friend, Thank you for posting your query through Healthcare magic. I also think that you were affected by a virus for the last one week. But that virus is not what you are talking about. Virus is a biological waste particle in your body as a result of the disease and not the cause of diseases. I am a Homoeopath and so you be prepared to hear something different about your diseases. The virus I meant was something in the dynamic level, a mental conflict. Since in your opinion these mental influences have no significance, you did not mention anything about that in your query. These mental conflicts made you sick to the level of reducing your immunity. This made you susceptible to diseases. The first disease was a conjunctivitis, a relatively harmless affection. But when you started suppressing it with local application, it went to a deeper levels producing deeper affections. Your conjunctivitis was in the ectodermal level but the period problem and the unusual tiredness was in the Neuro endocrine level. That is why you had a very bad period this time. All your hormonal system got shattered and you suffered unusually bad this time. Now my suggestion is that you should stop external application or medication to control conjunctivitis . It can be managed simply by frequent washing of eyes with pure cold water. You are advised to have constitutional treatment to strengthen and cleanse your constitution. I can confidently suggest you to take Homoeopathy for that. You have proved that your health is not very good because you have the history of cancer and getting periods only once in an year after chemotherapy. My concern is more about your constitution which reacts badly to any stimulation and my advice is to get Homoeopathic treatment from an expert. I can also help you provided you ask a premium question or you contact me directly with more details about YOU because Homoeopathy never treats your diseases but treats only YOU. With Best Wishes, Dr C. J. Varghese, Homoeopath, drcjvarghese@gmail.com,
