 Low back pain that radiates down into the leg but doesn't cause numbness or tingling in the foot can be caused by several conditions. Here are some possible causes: 1. **Muscle Strain or Sprain**:  Overuse or sudden movements can strain the muscles and ligaments in the lower back, causing pain that may radiate into the leg. 2. **Herniated Disc**:   When the soft center of a spinal disc pushes through a crack in the tougher exterior, it can irritate nearby nerves, causing pain that travels down the leg. However, if the disc herniation is minor or doesn't impinge directly on the nerves that lead to the foot, numbness or tingling might not occur. 3. **Degenerative Disc Disease**:  This condition involves the breakdown of discs in the spine due to aging, leading to pain that may radiate down the leg. Again, if nerve impingement is not significant, numbness or tingling may not occur. 4. **Facet Joint Dysfunction**:  The facet joints in the spine can become inflamed or injured, caus

I can provide some general information. Muscle relaxers are commonly prescribed for back and neck pain, but they can have sedative effects and may cause drowsiness. Some muscle relaxers that are known for causing less drowsiness include: 1. Tizanidine (Zanaflex)  It is a centrally acting alpha-2 adrenergic agonist that may have less sedative effects compared to some other muscle relaxers. 2. Cyclobenzaprine (Flexeril)  While it may cause drowsiness, some people find that the sedative effects are less pronounced compared to other muscle relaxers. It is typically taken at bedtime. 3. Methocarbamol (Robaxin)  It is another muscle relaxant that may have less sedative effects, although individual responses can vary. It's important to note that individual responses to medications vary, and what works well for one person may not work as well for another. Additionally, muscle relaxers are generally intended for short-term use, and long-term use should be discussed with a healthcare profess
