Rejoining of Indian Air Force

Dear sir, I have joined Indian Air Force as a co.batat member on 14.12.2000 in Non-Techical trade and completed my service 6.6 years as Clerk General duties. I have sought discharge on compassionate/Medical grounds of my parents. Since my childhood onwards I want to be an IAF personnel. Due to some consequences I opted discharge. Still I am eager to continue with my service. Ki dly guide me is there any provision in law for rejoining my service
