I am a male and 23 years old. I have many problems altogether and also checked with my gp and he is saying it is because of impure drinking water but I now drink only boiled water but still the things won't change Backpain Tailbone pain - a bit more Bloating Acidity Too much gas Lower abdominal pain Neck pain Hoarse voice sometimes And while taking deep breath i can feel phelgum in my wind pipe Irritation or a bit of burning sensation after urinal discharge I first thought the back and pain must be because I sit on bed the whole day with very minor movement of body but now as things are accumulated with others I can't understand. Please suggest anything or something to understand the issue going on with me
