What you're describing — your brain sending the signal but your leg not cooperating properly — is actually a very recognized experience for people with relapsing MS. It's not just muscle weakness; it's more about the communication breakdown between your nervous system and your muscles.
MS can damage the nerve pathways that carry signals from your brain down through the spinal cord to your legs. With multiple spinal problems already present, those signals can get disrupted or delayed, which is why a simple movement like a point-flex sequence can suddenly feel uncooperative or forced. A MyMSTeam member described something very similar — their knee would just buckle unexpectedly during what should have been a straightforward movement, with no obvious reason why.
This kind of coordination difficulty is commonly reported, and it can vary day to day. Things like fatigue, temperature changes, or simply doing too much can make it worse. Seeing your GP is absolutely the right move, especially given the wait for your neurologist. It's worth being very specific when describing what happened, including:
- The exact movement that failed (seated leg extension, point-flex sequence)
- That your leg felt uncooperative rather than just weak
- That you had to force the movement consciously
- When it happened and how long it lasted
Your GP may be able to refer you for physical therapy in the meantime, which has helped many people with MS manage coordination and leg weakness while waiting for specialist appointments. It's also worth asking your GP whether your neurologist appointment could be escalated given new or worsening symptoms — new coordination issues during a supervised exercise program is a clinically relevant change worth flagging sooner rather than later.
