This pain with resistance may indicate that tendonitis is a cause of your problem. Stiffness- Many tendons course through your body in a fibrous sheath, and when inflammation and swelling occurs, this flossing in the sheath becomes limited. This occurs with tendonitis, so stiffness after a period of rest may occur.
Concerta and Adderall are the brand names of generic medications. The generic form of Concerta is methylphenidate. Adderall is a combination of two generic drugs: amphetamine and dextroamphetamine. A side-by-side comparison of these two ADHD medications shows that theyâre similar in many ways. However, there are some differences.
AdderallÂ® is now available in an extended release version that lasts for 24 hours, called Adderall XRÂ® (an abbreviation for eXtended Release). Adderall XRÂ® is an extended-release version of the drug that only needs to be taken once daily and is only indicated for childhood and adult ADHD, not narcolepsy. The XR formulation is still patented, meaning that it will not be available in generic form until at least 2019.
