Pain getting too severe to allow me to work

Hello, I have not had to post on this forum since 2014 (?) as the pain I had was moderate and not so bad as to impair my daily work.
Lately the pain is getting so bad that I cannot work effectively or without a lot of pain. I did have regular injections which helped for quite awhile and now it the pain seems to have come back with a vengeance.
I am still able to work, but I fear that without some intervention I will have to reconsider.
I have no other means of income and I really need some help!
Many Thanks
Peter Allen
