Progesterone infusions have been studied for years. A doctor in Georgia has tried to patent the procedure. It works for some but must start immediately after the brain trauma as it acts as a neuroprotective agent to slow and prevent the cascade of damage that happens during the first few days after the brain trauma.

Your doctor may be talking about something else. I have not heard of any other IV therapies.

Your other doctors are clueless if they deny a concussion that did not have LOC. Very few concussions, likely less than 5%, include LOC.
