I have cerebral palsy that involves spasticity and tightness in my muscles is there any pills out there that can help they dont have harmful side effect. or any other recommendations outside of physical therapy. thank you very much?

Yes, anti-spasticity pills are available but have mediocre efficacy and multiple adverse effects. Other approaches could include BOTOX injections, acupuncture, various stretching programs, and a physical therapy approach called Red Cord (which may be unavailable where you reside). Lastly, some research protocols for newer agents using modified cannabinoids are available, but locations are?
