You have an issue that has been going on over two years. You have seen the terminal provider for the disc bulge, and the surgery did not help. That would seem to indicate that the surgery was unnecessary. Having symptoms that go down both legs, and burning and tingling in the back is not indicative of a disc herniation. Bilateral symptoms are much more common in chronic pain syndrome than they are for discal pathology.
You are extremely irritable as you report that you are unable to sit for an hour without severe pain. You've already had a consult with the Barbell Medicine team. You are unlikely to find a group that could get you back into lifting more effectively than them.
From my standpoint, I would highly suggest getting under the care of a Behavioral Health provider. There is certainly a psychosomatic component to this issue, as well as almost certainly a layer of depression or adjustment disorder in here as it relates to the changes in your lifestyle. In this case, a behavioral health provider is the best suited to take over your case from this point.
