My DH was recently diagnosed with a degenerative back condition. He's had physio and bought new running trainers which has helped, but aggravated it a couple of days ago doing some exercises in the gym. He now has a completely numb thigh as well as back pain. Because he can walk even with numbness, doctor says it is non urgent and has referred him so he has an appt with specialist in 2 weeks time. However he is a lot of discomfort particularly at night. He can't get comfy when lying down, has to get up and stretch a lot, and is suffering a lot. Lack of sleep isn't helping, so it's a vicious cirlce. Any advice on how he can ease the numbness/pain and get through the next two weeks before seeing the specialist?
