"Pain clinic"

I suffer from moderately severe osteoarthritis in both knees. I was referred to a pain clinic on 21/2 13 The consultant recommended some pain tablets and suggested acupuncture which I tried neither worked. Saw him again on 27/3/13 and it was suggested Itry something different this time it helped. But still had some pain 6/12/13 Saw consultant again but seemed very busy, suggested physio and patches. In no longer than 5 minutes 20/1 14 physio 10/2/14 physio Tried to book follow up appointment to discuss various options but have been told that he has discharged me. No reasons or consultation given
