My husband had resection of a GBM 4. After slowly regaining use of his left arm and hand he has quite a bit of pain. He has had an MRI, a pain conduction test, and takes meds for it. Nothing seems to help. In fact it is hurting now more than ever. It took about 2 months to regain use, but now he is pain all the time unless it is supported. Has anyone else had this experience? Did anything help? Thank you for sharing.
