My wife recently had an MRI done due to being awaken with pain in her left arm. The family doctor looked at the MRI but was very brief in there explanation. The family doctor did say that it was not MS. All the doctor said was that there was shadows shown on my wife’s brain that were 4-5mm. The family doctor has now sent us to a neurologist. The only problem is that we have to wait 4 weeks till we can get in to see the neurologist. This kind of news makes one think of the worst. We are going through hell trying to figure out what this all could be. What are common prognoses for shadows on the brain that are 4-5mm in size? I am going nuts !!
