Can someone help me? My daughter is 16 and was diagnosed with PID. Her pain has been unbearable and its killing me... She's been on meds for 4 days. I know it'll take time to start helping, but she's having a horrible time walking. Her left leg doesn't want to seem to work and she says it feels like stabbing pains are running through it. Its bad enough she has to lift it to just lay down. Its a little swollen. We've been to her doctor and er twice. Is this normal? I just wandered if anyone else with PID has gone through this??
