Does Anyone Here Have Degenerative Arthrosis (aka. degenerative osteoarthritis)& How You Deal With The Pain ?

I wonder how people with degenerative arthrosis also known as degenerative arhtritis or degenerative osteoarthritis, have deal with the unbearable pain and work. Have this condition stop you from working ? How can I return to work, and with what medications to kill the severe pain on my feet and knees joints ? I dont want to become bedwritten, Im only 29 years old and already have Degenerative Arthrosis on my both feet & both knees, periostitis atributed to enthesopathy, tendinitis, synovitis,crps, rsd, a fracture on my foot that havent healed yet in 5 years since it happened, etc, not to mention the depresion this have caused me, but im not giving up yet. Althouht im in a lot of constant severe pain, I will like to know if this condition will get less painfull with time or if is going to get worst and what can I do, since doctors are afraid to give straight answers on this questions. Anyone suffering from any of this conditions, I will appreciate any comments on this. Thanks.
