Lastly, even if new symptoms are emerging or worsening directly as a result of your MS, it doesn't mean the MS is getting worse. Some symptoms seem to emerge more commonly during the recovery phase of relapses and would indicate attempts at regeneration or scaring.
This is why you need the help of an experienced MS specialist to sort out these issues and help you find the appropriate treatment. These are complex issues and even a skilled MS specialist will often find it difficult to determine at first to determine if your worsening symptoms are directly attributable to your MS. However, the cause usually becomes apparent over time. I hope this information helps.
