Hi Clare,
Weakness and numbness - anywhere - are very common (I would say almost universal) symptoms of MS.
From the forum you’ve chosen to post in, I’m assuming you don’t yet have an MS diagnosis, so this symptom, alone, cannot prove what it is.
I’m afraid I don’t know of any prescription or DIY remedy that helps with numbness. It’s usually caused by damage to the nerve pathways stopping signals getting through, so unless or until the damage repairs itself, allowing signals to pass again, there’s probably nothing you can do to restore “normal” sensation.
The good news is that, for most people with MS, the damage does eventually repair itself - though not always perfectly - so there is a good chance of regaining most of the sensation. Repairs are slow though, so you might just have to live with it in the meantime.
If an attack is very severe, steroids are sometimes offered to speed up the repairs, but they have risks and side-effects of their own, so sometimes it’s better to be patient, and leave nature to do the work.
Although numbness can’t usually be cured, some people find it’s possible to temporarily distract from it, by applying heat or cold. If the numbness takes the form of feeling as if a tight garment is on the affected part, it can help to put a tight garment on it for real! I know this sounds mad, but your brain won’t find the numbness so uncomfortable if it thinks there is a valid explanation - e.g. example that you are wearing tight clothing.
Weakness can sometimes be addressed by specialist physiotherapy. Ideally, you need a neuro-physio, not just any physio, because they will understand the problems that can be caused when your brain sometimes can’t get signals to your muscles properly.
Hope this helps,
Tina
