Very similar story here, 48 hour soccer tournament, missed first concussion, then multiple minor concussions with headers and an elbow to the head. We are 7 months out. Look into P.O.T syndrome for the numbness in hands / feet issue, a good neurologist or cardiologist will diagnose this. Postural Orthostatic tachycardia syndrome - common with multiple TBIs. Our third neurologist recommended DHE IV therapy, we had constant intractable headache/ migraines, worked somewhat. Understand the wanting pain stopped. Good luck.
