I do hope you can find another physician. However going to a walk in clinic, you will not be satisfied and helped enough. You do need a pain specialist, that deals with this all the time. This is the best route to getting some help. No regular doctors these days, want to prescrible meds on a regular basis in this type of clinic. You don't want a fly by night kind of place either.
I interviewed 4 doctors that specialized in pain management. The one I picked was also a physiasist. Yes she prescribed enough, and lets me decide. I am allowed 4 per day. I usually stick with one unless I am really on my feet a long time. I do take another, twice a day, and have for the past few years. Again, I do hope you all the best. Bring all your records, and keep a pain chart if possible. Pain specialists, do like it whn you record your symptoms, what makes it worse, times, duration etc. ginnie
