Stortie, I hope you're sorted out now.
I'm pleased to report that the swelling is reducing since I stopped taking Amantadine. My ankles are still noticeably puffy, but not swollen and rigid like they were before. It was definitely a side-effect of the drug.
FYI. I was prescribed Amantadine to extend the effectiveness of SInemet. I was having pronounced Off periods towards the end of doses (8am, 12, 3pm, 6pm). All my symptoms became more pronounced. Amantadine helped, but seemingly by making me feel 80% of myself all the time, rather than 100% when 'On' Sinemet (most of the time), reducing to 50% as the Sinemet dose wore off. Having stopped the Amantadine now, I prefer the 100/50 combo. I hated feeling so dopey for so long!
