Peripheral neuropathy can be in legs, feet, hands and arms. Yes I'm still working but PT due to many issues in addition to neuropathy in hands, feet and up one leg almost to the knees. I'm semi-retired and I'm almost 60 yrs old. There are medications that can help such as gabapentin, amytriptyline, SSRIs (antidepressants), etc. A neurologist can help u find the right med. I also wears compression stockings specifically for neuropathy and orthotic sneakers for extra support. It's the lack of feeling or sensation when walking to be able to know if they are solidly on the ground. I look at my feet often to double check especially when on uneven surfaces. With the hand numbness, get tested for carpal tunnel syndrome to rule that out because the treatment can be as simple as wearing wrist splints. Do your research for options available. Try not to self diagnose and convince yourself u have this or that. Do it just for informational purposes in order to advocate for yourself and get the Dr's opinion on your findings. By the sound of your message you're already "preparing" to not be able to take care of your children. Don't allow yourself to go "down the rabbit hole" Don't go too far ahead of yourself. Regards.
