To Run or Not To Run?

Assalamualaikum & Goodday
.
My left shin is killing me. It hurts when i run. And i dunno why. There are no bruises and it doesnt swell either. Only when i run it hurts. I'm so sure i didnt knock on anything recently. Or did I?
.
What pisses me off the most is that it throws a monkey wrench into my running program. Everytime i run, i couldnt finish it or the timing is way out of my target. I think my shin conked out oredi la.
.
Do i need to go to the doctor? Not ready yet. I think i'll let it be for a while. If this aching is not gone after a month, i'll go. Malu lah eh, baru lari sket-sket dah nak pg jumpa doctor.
.
Oh yea....i've been following this running program by Nike. So far so good lah. It helps to build up my stamina. The drawback is that i have to restart what i've started earlier. I had to start with a very short distance and gradually increasing the distance.
.
Consequently, i'm gaining weight again :( Apparently the low milage is hampering the fat burning process. But i'm not that worried lah. It's just temporary. Once i hit my normal mileage back, i think i'll be able to shed some fat. Amin....

There are indications that my career my will hit another milestone. I oso dunno whether it's a good thing or a bad one. It's not confirmed yet. But the news was conveyed to me directly by the Civil Servants' Don of Perak. But i think i shall keep it to myself until the black & white arrives. So tunggu eh.
