My son was struck in football & has suffered a severe concussion.  He has a soft lump at the back of his head if barely touched (just brushed) he gets dizzy & naseous.  The MRI is clear there is no sign of the lump. Does he need as X-ray, CT scan or other test to see the lump?  Should we seek a 2nd opinion
After MRI no need for other test as it picks up soft and bony parts both abnormalities in my patient I would have not gone for second opinion immediately would have given rest and time for injured part to heal would not have allowed examination or physical touching or pressing the injured part. All these will hinder healing If possible cold ice fomentation to local part may be applied light painkiller may be UED if it is very painfulIfSome new symptom develop like repeated vomiting loss of consciousness confusion memory disturbance do go for second opinion and other tests, but hopefully it may not be required he needs encouragement and happy environment Be positive and take care Chat Doctor.
