Hi, i fell whilst walking my dog four weeks ago and head butted the concrete really hard, i did not lose conscience and picked myself up quickly but needed to sit down as felt really sick and faint, woke up next more with a badly swollen black eye and bye the second day i had two very swollen black eyes. i am still left with a lump which can feel very sore and niggarly at times on my eyebrow line, will this sort itself in time as am not suffering from headaches or anything.
