It is possible that therapeutic cannabis in cream or oil form could be effective for pain relief. However, determining the correct dosage can be tricky, especially if your doctor has referred you to a specific outlet for obtaining it. It's important to have a discussion with your healthcare provider to explore other treatment options and ensure that a comprehensive treatment plan is in place to address your specific condition. Physiotherapy or physical rehabilitation may also be beneficial in addition to considering therapeutic cannabis as a potential treatment. Remember to consult with your doctor and pharmacist to discuss all possible options for your care.
