Jethro,
I understand [as much as a CALS can] your frustration. There's a lot of territory between NurOwn and a gun, that qualifies not as "healing yourself," but as "helping yourself live better." We've had several threads about the ways that people here extend the quality and quantity of their lives. These include:
Active-to-passive range of motion exercises
Massage to prevent/reduce edema
Respiratory support as soon as needed, with adequate secretion removal
Mobility devices to avoid falls, likely culminating in a power wheelchair with elevation, tilt, recline, power foot rests
A bed that allows for an optimal position to avoid pressure injuries and facilitate lift transfers
Maintaining body weight, through nutrition and hydration, via tube if/as needed for adequate intake
Judicious use of supplements (several threads)
Adequate sleep, social/nature/arts interaction, continuation of hobbies/pursuit of interests adaptively if possible
I could go on, but you get the idea. We do not know what the future holds in terms of treatments and availability, but maintaining your ability to benefit and maintaining your own best "standard of care" is a pretty no-lose strategy.
Best,
Laurie
