How are you now?
DId you see your dr?
Are you still having high blood sugars?
Hi there!
Blood drawn from the veins is usually dark and has nothing to do with glucose levels. Most systemic causes such as infections may be associated with temporarily increased blood glucose levels. I would suggest consulting a primary care physician for a detailed evaluation regarding the fever and headache. After a cause is identified it can be managed accordingly. It might also be worthwhile to consult your endocrinologist for control of blood sugar levels.
Hope this is helpful.
Take care!
