Hello
Ur problem seem to me similar to the problem which we discussed under the heading..increased pain due to lumbar traction.my patient also had similar complaints..
This phenomena is called pheripherilistion..which is not considered a good sign in recovery.Try treating his back with unilateral lumbar traction and Unilateral PA ,also rule out any local problem to the muscle...u can even try Ift to the lower back ,i have got good results in some patients with refeered pain
Regards
Sana
