Out of cast after 4 weeks(long arm) muscles in forearm tight n painful n numbness in thumb normal post cast? i had epychondolitis n torn tendon

Can be expected --: Stiffness from being in a cast for 4 weeks. Numbness maybe from cast being too tight or the cotton padding may have bunched up causing a local neuritis, which should clear up in 2-3 weeks time. As you exercise the tight muscles should loosen up and get stronger, reducing the stiffness as well. Massage/stretching exercises would help the epicondylitis. The doc should advise re: the torn tendon!
