Hi, I have been experiencing a bitter and abnormal taste on my tongue for past two months .But when I eat something sweet,salt or spice I can taste the foods items as they are. I feel burning sensation post urination which lasts for around 15 to 30 seconds. And urine appears to be a bit foamy . I am also experiencing upper abdominal discomfort which shows up early morning in between 4 to 6 Am.It settles down as the day goes on. I have not been able to sleep properly for past 5 months .usually wake up inbetween 2 to 4 in the morning.Its difficult to fall asleep after that. Since past 5 days I am experiencing stiffness in my lower legs and fatigue overall,Frontal headache which is not going away.And developed symptoms of mild nausea n dizziness. Note: Non Alcoholic and non smoker. Diet is mostly high protein and more of fruits n veggies. Thanks, Vishnu
