Still no relief for swollen S1 nerve - am 4 weeks post-op and had nerve root injection 10 days ago. I notice that the pain management consultant says in his letter 'she may need a second injection' . Has anyone had experience of steroid injections for swollen/inflamed nerves after surgery ? I had them pre-surgery and got a great response but this one doesn't seem to have done anything ! frown emoticon My foot pain is killing me !
