Any health advice would be appreciated!!?

I've had similar symptoms. My diagnosis was Anemia. I was low in iron, and that causes you to feel tired, and weak, the chest tightens and your heart will feel the pressure. Iron helps the red blood cells move around the body, and the red blood cells carry oxygen. You could be worrired about something, you may be thinking a lot, that can cause the symptoms you've listed. Thinking too hard is another form of stress. Diet is another possibility, you may be lacking vital vitamins and minerals, may be eating too little or too much of the wrong things. The NHS website will help you more. Just type in your symptoms. a href="http://nhs.co.uk" rel="nofollow"http://nhs.co.uk/a I hope you get better. X
