Hi Dear you got a fall in your bath room ,following that you had a
concussion according to your doctor,and swelling on side of your head,and now bruising over your
upper lip,one important thing you had not mentioned in your question was
CT scan done at that time and if so what was its report.this
bruise you mentioning is most probably a haemotoma (collection of blood under skin or muscle) ,which you had got time of fall and it has spread dawn,it will disappear of its own,or may need,local application of thromophob ointment (
heparin ointment),with some antibiotic and enzymes,if it is bigger one,but the important thing is if you had not done CT scan at that time get it done now,though chances that you may have some problems inside your head is quite less ,but still to rule out,any thing,small haemotoma or fracture
