Anybody had colodial injections?

[Craphouserat]

Second back op in April hasn't worked. Visited works doc yeterday as they wanted independant assesment of my condition - I didnt take any of my usual painkillers before i went (dihydro'-tramadol ets) so he could see extent of pain - could barely walk and was actually in tears in room with him. have my op foloow up in jsut over a week - drop to half wages today. stting myself about next step - I dont want anymore ops - the doc said although hes no specialist he reckons I'll be told its painkillers for good or I'll be offered colodial injections - think thats what he said - he was only there to asses me from a works point of view - i cant work right now. Visit my own gp to day to discuss my pain relief - hoping to get back on Pregabalin - this worked well for me pre-op earlier this year. Just wondered if anybody here have had these injections?
