How long would a torn muscle in your back take to heal?

Varies: If it is really a simple lumbar strin, which is the medical term for a muscular injury to the back, you should be better within 10-14 days. If you aren't better after that, there is probably something more going on and you may need an exam and possibly an mri. Thank you for the question.

Fast Healing: A sprain is when a ligament or tendon is injured by overstretching. There may be minimal or quite a bit of damage to it. Inflammation (redness, warmth, tenderness, and swelling) occurs as a natural healing process. The key is to minimize further damage while keeping the area flexible and mobile. Ice massage (24-36 hours), rest, gentle range of motion are the keys to maximize healing.
