### output:

Hi, You may very well be suffering from post-concussion syn Chat Doctor.  I am concerned about damage to your brain which will explain the loss of feeling in the right foot and then, vertigo or spinning as a chronic symptom that may never get better unless you literally give your brain a significant amount of time off.  Your mood swings may also be an indication that the concussions you've had been beginning to accumulate to critical levels and potentially could be affecting your personality and behavior to a point where people may even think you have anger management issues (and you just may at that).  You should be evaluated by a neurologist knowledgeable in TBI's and concussive sports injuries because there are tests that will help locate and define the problem.  You can clearly benefit from an MRI of the brain (at least) as well as blood work and some other tests to get a better handle on what these symptoms are not.  If you continue as you are and do not suspend activities as a boxer you are risking permanent and even escalated damages than what may have already occurred.  I know this since I treat many veterans of wars who experience very severe traumatic brain injuries (TBI's) from IED blasts, falls, and motor vehicle accidents. Many will end up with permanent symptoms of damage that are similar if not exactly as yours with some symptoms. Hope I have answered your query. Let me know if I can assist you further.
