I'll take a peek at those pics in a minute.   But first let me say that they
are finding new things that help pain like yours all the time.  If the
electric shock stuff works, then a lot of your pain could be from muscle
spasms and inflammation.   The right therapies can sometimes relieve a lot
of that.   I sympathize because I have had a very bad back all of my life.
I bought a special foam mattress that helps sometimes, and even still,
sometimes sleeping in a recliner is the only thing that helps.

I have a whole collection of drugs for the problem, and to tell you the
truth, the ones that relax the muscles and relieve inflammation are the ones
I get the best results from.   The pain killers don't do much but just for a
couple of hours and then the pain comes back, so I do know how relentless it
can be, but I think your injuries are worse than mine.    If the
conventional therapies don't work, then try some of the unconventional ones.

I have another lady friend who was told she'd never walk again.   Well, she
walks quite a lot now, and coping with her pain takes a huge amount of
effort, but her best therapy turned out to be swimming.   She actually has a
swimming pool in her garage with a motor that makes a current for her to
swim against.  Without it she'd be totally crippled.   She even has a
successful business repairing musical instruments.  Sometimes she can only
lay on the floor while she repairs them, believe it or not!    She wears a
back brace and is constantly going to massage therapists and (very gentle)
chiropractors and acupuncturists and whatever.   But she has managed to find
a life and become successful, even though she was nearly crippled for life
and her international music career was stopped dead after her accident.

She is really an inspiration, though she is in constant severe pain, like
you are going through.  Even if you can't get rid of the pain, you might
find ways to manage it so it is more bearable.   Staying in the best of
health you can is only going to help with that.

Keep your courage up and don't lose hope no matter how bleak it seems
sometimes.

Now I will go look at those pictures!
