As Nikki has already told you, the drugs are not cures and there are side effects and controversies with both. I would encourage you to start a daily habit of stretching and staying well hydrated. This can help with muscle memory which is important towards long term recovery and to prevent atrophy. I lived in Fairfax for about a year and a half and you have many places to workout low impact exercises such as yoga, tai-chi, and pool therapy. These workouts can greatly benefit you in recovering. Unfortunately, whether meds or exercise, there is likely to always be residual damage from the lesions. You can, however, use the stretching and exercising to aid in each recovery. Your current one sided weakness may dissipate on its own. While you are waiting, this is where the stretching plays a role in maintaining your tone and muscle memory.
In deciding to use any med or not, read about the med and their warnings and side effects. Ultimately. it will be up to you to know if they are helping or not. Your doctor should also be providing with you with any necessary monitoring which can help you know when you might need to stop taking a med or to change a med.
