Back of Head meets Cement Slab awaiting consequences.... No headache, slight 'disorientation' for a few minutes while attempting to rise off back on slab. No other signs for first 36 hours or so.... Did not go to ER or DR or Hosp. Applied extreme caution for first 20 hours or so (With 8 hours of first night sleep followed by 3 to 5 hours - following day) Slight activity for Nxt few hours - Assembling metal 'rolling cart' , Lught weight handling etc... ) Yet on 2nd Morning after incident began to have symptoms of 'balance issues' .. I am a senior (70 plus) with no prior 'Head trauma' but on several meds (BP, Thinner - 3 Stints over some 15 YRS, Chelosterol) Should I be concerned as with no symptoms first 24 hours, I have not seen a DR) .... Appreciate all replies ... Thanks ....
