[|Human|] Hello, I had a question regarding concussions or hard hits to the head and immediate as well as prolonged smell senstation. I ve had more than a couple of hits to the head from explosions in Iraq to wrestling to mountain biking falls. Everytime I hit my head Ive had a copper-kind of smell for awhile and as of about a year, i ve had a that strange smell (which seems inside of my head) more days than not. I see fine, I do have a constant faint ringing in my head or ears for which i m going to see the ear doc. I failed some tests at the traumatic brain injury center which involved drawing lines from 1 to A to 2 to B to 3 to C etc. I have an issue forgetting things etc. The MRI is fine but for over a year I have been given no real answer. I also have some constant but faint headaches which they called occipital neuralgia . I appreciate any thouhghts. v/r J.
[|AI|]  Hi, Thank you for posting your query. It is unfortunate that you have problems for so long after the head injuries, and moreover, no proper diagnosis has been made. Your symptoms are suggestive of concussion and all the symptoms can be explained on its basis. Normal MRI rules out any major problem or injury in the brain. Abnormal sense of smell is related to partial damage to olfactory nerves or its central connections. We expect gradual recovery in your symptoms, however, it may not be complete. I hope it helps. Please get back if you require any additional information. Best wishes, Chat Doctor. Ly/
