Having awful muscle spasms in lower right back and hip area. i take tylenol (acetaminophen) 3 and flexeril, but doesnt provide much relief , what do i do now?

Can you change: Tylenol (acetaminophen) to an anti inflammation drug like ibuprofen (4 3 times a day or aleve 3 2 times a day) and use moist heat or ice whichever works best. You might need physical therapy.

See a doctor: This could be many things, such you sprained or strained your back or lumbar degenerative disc disease, etc. I recommend you see a doctor to get a full exam and possible need radiology study to find the causes. There's treatment for it, including physical therapy, injection or medication, but your doctor has to find the cause first.
