Shin splint. & started taking.

I would describe my problem from beginning. I generally used to run 1km till 2015. I started to increase my run from feb'16. I used to run 5 km and 10 km till December'16. In the mean time,I suffered from shin splint. Initially I was not concerned but pain was increasing so physiotherist suggested me to take rest for 1 month.Then I took again 1 month and stared running. It was happened many time in 2017 but could not healed properly. After then in Mar'18, I started to take medicine from one orthopedician (specialist). He asked me to take rest 3 month and give some medicine for 3 month.After 3 months i started gym to strengthen my calf's.One day I run 5min on treadmill then I felt some vibration in shin splint then I left running and continued gym. When I increasd bit more calf's exercise then started soft pain in leg.Please suggest , whether I can run or not in my life. Somebody suggested me to take extra protein powder to heal and strengthen leg as I am vegetarian & started taking.
