I Have A Chiropractic Question. I Have Recently Started Seeing

I have a Chiropractic question. I have recently started seeing a chiropractor for the first time about some back pain issues. He took x-rays on my first visit and said that from L3-S2 when I bent to the side there was no movement. He has done some therapy with the Tens unit to relax the muscles but the only thing he has done is lay me on the table and flex my lower back using the table to loosen it up. He says that it is starting to loosen up but I have been to 5 visits now and he has done the same thing every visit and I have gotten no relief. Should I consider going to another chiropractor or is what he is doing the proper way to handle it. I am still in and extreme amount of pain and cannot stand straight up due to the pain in the muscles and I can also feel the tightness in my spine. He has done no adjustments besides the one stretch on the table. Spends less than 5 minutes on the issue. Should he be doing a good adjustment or is he working it properly. I also have a partial bulging disk in L4 and L5.
Thanks
