Hello friend
I have read your query with great interest and will try to help you
First, I dont think that the shaking of the hands is due to the lack of
oxygen, not in your case that is. The lack of oxygen can cause shivering and more commonly seizures. But in your case it is unlikely to be due to lack of oxygen.
You have had
cough for 6 weeks. Now that is a very important symptom and you should get an
x ray of the chest and sputum examination (AFB) tested as soon as possible.
This is important because you may have been developing the symptoms due to
tuberculosis. So it would be essential to rule out this symptom.
I also feel that the long illness may have affected your diet. So if you are eating less, there is a possibility that the symptoms are due to the lack of food, and a generalized weakness.
So I would suggest eat well. And get the tests
Let us know the tests so we can help you better
Best of luck
