<human>: almost 4 months ago i tripped down some stairs and hit my forehead against the wall. i had a huge lump that was there for about 2 weeks including black eyes that healed after 2months...finally after that the lump became smaller i started to feel sharp almost needle like pains on the lump. the lump hasnt fully went away but now i do see a small dent on the top of my forehead. could this be a serious matter that i should get an MRi for?
<bot>: Hi. The typical pain is due to the nerves getting reattached to each other differently during the healing process. This is called paresthesia. This is usually a self limiting disease. IF you feel it is troublesome you can get a prescription for the medicines to reduce this type of pain. The trauma which has caused such a severe problem should have been investigated . By a CT scan as the bone defects are better in a CT scan than an MRI. CT will also show other parts of the brain and all.  Go for a CT scan
