Hi and welcome,
MS is too complicated to be ruled out because of a 6 month consistency of your symptoms, IF your symptoms had 'rapidly' multiplied, 'rapidly' spread all over, 'rapidly' worsened etc over that short a time frame, MS would be a very unlikely causation because MS lesion damage doesn't typically do that type of symptom pattern...
It is actually possible to have MS for many years and not know it until a specifically located brain and or spinal cord lesion causes something to be significant enough to get your attention. Brain lesions can develop without causing any symptoms, symptoms will vary, as will their intensity based on the lesion location andunfortunately full recovery is not always possible eg
"The cerebellum controls and corrects all body movements so when there is damage there, it can result in poor balance or coordination. This can even cause difficulty grasping small objects, writing clearly, or keeping a steady hand. When walking across a room, it's not uncommon to lose your balance, as if you were drunk.
Balance & coordination problems can include:
● Loss of balance
● Unstable walking (ataxia)
● Dizziness (vertigo)
● Clumsiness of a limb
● Lack of coordination
● Weakness - primarily affecting the legs and walking"
Lesion damage can cause consistent symptoms after an MS attack but please keep in mind that even though MS can definitely cause permanent symptoms, what your dealing with may honestly 'not' be a neurological condition like MS......try if you can to stay open minded on what it could be at this stage of testing!
Hope that helps......JJ
