How long does it take upper right back strain to heal. I have had six weeks?

Upper right back strain recovery time can vary depending on several factors, including the severity of the strain and the individual's overall health and healing capacity. However, on average, it can take around 2-4 weeks for a mild upper right back strain to heal, and up to 8-12 weeks for a more severe strain.

Since you mentioned you've had a six-week strain, it's possible that the strain is taking longer to heal or may require additional treatment or rehabilitation. It is always best to consult with a healthcare professional, such as a doctor or physiotherapist, for an accurate assessment and guidance on the expected healing time and necessary steps to promote healing and prevent further injury.
