Sudden right leg numbness

I have recently - 2 weeks ago within seconds lost the feeling in my lower back and the whole of the right leg movement still present has anyone else experienced it and has it resolved.

Hello Pammie,

Sorry to hear of your problem. Have you been dx with MS if not I would advise you to visit your GP and see what they have to say? If you have been dx may I suggest that when you see your GP you ask for a referral to a Neuro or a Rheumatologist as what you have described could be caused by many different things. It is possible you have slipped a disc which would affect you in the way you describe or caused by something else. It is difficult to say one way or another.

I’ve had total numbness of pelvic region and both feet before.

Numbness is a common symptom of MS.

It didn’t come on in literally seconds, but quite fast. I went to bed OK, but woke up…not. In my case it was due to a spinal cord lesion, and I eventually went on to be diagnosed with MS. But I was investigated for a slipped disc first. Because, as Janet says, this is a possible reason for loss of sensation in the lower body.

If you are a diagnosed person, I would think relapse is the most likely explanation, but I’ve never had one come on that instantly, which makes it sound more like an injury. Can you recall what you were doing at the time? (Lifting? Leaning awkwardly?)

Mine - which was MS - did resolve by the way - but very slowly. Almost a year to recover completely (nearly completely). There was some progress before that, though - just very, very, slow.



With all sincerity and sense of urgency, whether diagnosed or not, a sudden / dramatic change in any negative respect is not to be procrastinated over. Do something more than hope for optimism from online strangers.

Anything sudden, i go to the Emergency Ward. Why wait?

As a diagnosed person, I’d be very unlikely ever to go to A&E with anything that’s a known symptom of MS - especially after my last experience there, which I had no choice about, as I’d been in an accident.

I spent over eight hours on a trolley, with nothing to see, do, or read, absolutely no food, and one cup of tea the whole time. I was running out of Baclofen, and despite it being a hospital, not at all optimistic about the chances of them procuring any for me - or at least, not within a reasonable time - i.e. before I was cramping from head to foot or getting a withdrawal reaction.

I certainly couldn’t recommend it for anything that wasn’t absolutely desperate, and nothing that happened two weeks ago is a medical emergency.

Normal GP appointment for this one - A&E already can’t cope - and didn’t have a clue about MS.


I am glad to be in Canada.

And i am even more glad that the last provocation for me to visit the local A&E (whether they are known to be forthcoming with adequate refreshments or not) was not due to my having a stroke.

Not all things known to be caused by MS are caused by MS.

Frankly I could not care less if the local health care facility can ‘cope’ (from one’s own limited perspective), it is all about my being able to cope with what i have to deal with on a constant and daily basis. the very first step in achieving this, is sorting out new health issues, from residual MS grumblings.

Thank you for all your replays yes been diagnosed for the past 20 years with optic neuritis since then had it 6 times always resolved but only recently had problems 3 years ago I lost sensation in fingers in left hand never got feeling back but leg problem happened so quickly felt dizzy for a minute the when I went to stand up realised leg feeling and foot sensation gone I am now booked in to have MRI but don’t get any results till jan I am off work which I hate and mobility is rubbish even when I have tried a stick as I don’t know when foot is on the floor so falling

Hi Pammie,

I was diagnosed in 2000 and have had several relapses that started with sudden numbness. I have relapses now, once about every 4 years and this year is 4 years from my last.

I had sudden numbness on my left side. I had to go back to the UK for my father’s 80th birthday and just had to wing it. It has definitely been a relapse as it has rumbled on, affecting all sorts of things all summer.

4 years ago, I’d have had steroids, but as I’m in my 50s and I read the Barts blog each day, I have reluctantly decided that the risks aren’t worth it. The Profs and docs at Barts don’t recommend steroids due to a risk of the ball joint in one of the hips breaking and I’m about to get a new knee.

I can’t say that this summer was much fun, as the MS bit me in the rump many times. I’m still not quite over it, but I’m keeping my fingers crossed and hoping for more energy soon.

What I’m trying to say, is yes, sudden numbness can happen. Its worth reporting so that the neuro team know that your MS is active.

I hope you manage to rest and keep on with normal activities.

Best wishes,


Thank you so much for your comment. In touch with neurologist and seen MS nurse Bloods done today and waiting for MRI. I have also just bought a stick reluctantly hope it stops the wobbling. I have had iv steroids in the past and although quickened Optic neuritis recovery side effect very unpleasant. Just worried as lost feeling in part of left hand few tears ago that hasn’t resolved if foot stops me from driving will be pretty much housebound but early days so will cross fingers xx
