Thank you for your reply Chris, i will take everything you said into consideration.
The blood of which i speak is not coughed up, it is just mixed in, perhaps 50/50 with the coated mouth and saliva, and particularly upon awakening. After 4 days of this being about 50% of what i spit out, it was substantially lighter this morning and there was no blood mixed with my spit today.
ECG and other testing sounds great, i'd really like to know what's going on there... while also putting a lot of faith in my fasting body to heal itself.
Reached the 20 day milestone today en route to hopeful completion.
