is this a cause for concern?

so about 2 months ago i was diagnosed with osteoarthritis in my spine, along with epidural lipamatosis and herniated disks on multiple levels… i’ve been referred to a neurologist but been told it can take up to 3+ years for an appointment…

i’m in pain daily, but now i’ve noticed my right leg burns of a night time then it goes numb and i can’t feel it… it’s also hard to get up off a chair it’s like my legs don’t want to work, i’m worried i’m slowly losing sensation in my legs and i’ll become paralysed 😭 should i see my gp again?
