So i have been waking up with random bruises. my bones and body feel weak/cracking. my doc did a full panel + urinary test. will that be able to tell me if something is wrong. someone told me it could be low iron. will the bruising go away?

There are many possible causes of easy bruising. It is good that you saw your doctor and blood work was done. There could be something wrong with your ability to form a clot. It could be a problem with your blood counts or a host of other etiologies. You need to follow up with your doctor after the blood test results are available to see exactly what it shows and take it from there. Good luck to y
