MY Father Is 90 Yrs. Old. He Suffered With Weakness,

MY father is 90 yrs. old. He suffered with weakness, after standing for a few minutes. He is cancer patient. My family thought this was caused by the medications he was taking for the cancer. According to his cancer, cardiologist, internal doctors, stated that can't find the solution to this problem. My father went to Chiropractor today, xrays show that Degenerative Disc is the issue. According to this doctor, cold laser therapy along with other treatments to reduce the compression and help the nerves in around the discs to become less inflamed. It will be up to 12 treatments. Is this a good treatment for Degenerative Disc. ?
