### input:
Hello, I am a 44 year old male who, until relatively recently, has been very fit all of his life, playing various sports, particularly football until only a couple of years ago. My problem started at the beginning of 2009 when suddenly I lost all vision in my right eye. There was no pain and no warning signs this was going to happen as I had no previous health problems. This lasted for about 3 mins until the vision returned as quickly as it went.I had a number of similar episodes over the next few months including what I can only describe as a curtain dropping down in my eye (always the right eye). I was examined by various specialists and was diagnosed with Amaurosis Fugax and placed on medication (aspirin and ezetimibe). Afterwards I felt that my physical strength had diminished a little but still felt relatively fit.I was free of any further symptoms for 3 years until a similar episode of loss of vision in September 2012 and after further examinations my medication was changed ( chlopidigrel and rusovostatin). I felt that I was getting tired very easily and was finding it hard to concentrate at times. Again I was symptom free for about a year until I suffered a further loss of sight in my right eye (October 2013). Not only did I lose my sight, I also lost coordination in my legs, I had tingling in my right fingers and leg. I was admitted to hospital where I was told I was having a stroke. At this point I felt completely drained of all energy, I was sleeping most of the day, I had no strength in my arms or legs and was extremely moody. Over the next few weeks I underwent further examinations including a transoesophogal echocardiogram and it was discovered I had a Patent Foramen Ovale (PFO) which it was explained is a hole in the heart and was probably where small blood clots are forming. I underwent an MRI scan recently and it was found I had a white spot on the left side of my brain which was explained May be a restriction in the blood flow. I have been referred to a cardiologist and a neurologist for further consultation but I have to wait a significant time before my appointments. I am extremely worried as I have never had anything like this before, I am not allowed to work (I am a police officer of 23 years with minimal sickness) and do not know what is likely to happen.Any advice would be welcome.Kind regards,Eamonn

HAI it is nice that your narration of symptoms is so clear. Initially your symptoms were due to amaurosis fugal i.e. a transient loss of vision. You were advised aspirin, clopidogrel to prevent clotting of blood by their antiplatelet action and also rosuvastatin for cholesterol lowering effect. Your symptoms of defective right eye vision weakness and paresthesia in right upper and lower limb weakness suggests a lesion in the left brain. The white dot in MRI may be due to infarct of the brain, or a granuloma or a tumor.don't worry about that white lesion. Just follow doctors advise. Please do regular physiotherapy and use medication regularly. Avoid smoking alcohol and fatty diet.don't worry about patent foramen oval. Please consult cardiologist, and he may advise devise closure procedure if required.
