Talk to Neuro Psychiatrist on Nerves Issue

My sister has been facing nerves issue since last 23 years. She had consulted numerous doctors in Quetta and visited liaquat national back in 2014. But her disease is still not diagnosed. Her hands got numb and stiffed in the beginning of this issue but with the passage of time the issue has increased now her hands foot and almost whole body gets stiffed after every couple of days. In this condition she is even unable to talk and her throat gets dry. Since last year she has facing stomach inflammation along with hands and foot. If she is better she still has something wrong with her health issues due to which she cannt get relaxed and perform home chores. If she gets worried on even small stuff it ultimately triggers her this condition. She is facing weak memory issue and gets hyper over small things. Just because of her condition she is loosing hope of getting well.
