I am 68 year old male who was diagnosed with Parkinson's 8 years ago. Recently I sustained an injury to my lower back/hip area that was diagnosed as a strained QL muscle. My PT told me to slow down with my workouts and physical activities so I did but I continued to have extremely painful and debilitating spasms in the area of the injury. How this ties in with my Parkinson's is I realized that when I was having an off time with my carbidopa/levodopa therapy my body would tense-up triggering a spasm in my QL muscle. After doing PT, ice/heat, lidocain shot and finally dry needling, I think it finally calmed down, YAY! Anyway, I just wanted to share this with you all just in case you ever have the misfortune of injuring your QL (Quadratus Lumborum).
Cheers, Craig
