Pls Help (Persistent Pang)

[lotsoftime]

Not sure what a pang is. Can you describe it a bit better? What do you do before the pangs start? Are you eating enough? I know you got your shit straight from lookin' at your log. Taking anything else that may effect this?

Well it is not easy because I never felt anything like that before in my life!
It starts as a twinge, then becomes a pang and thereafter a persistent stab.

I feel, mostly after drinking liquid protein (42g in 100ml) a little pain at first in the lower right back but not too low toward my gluteal more up toward my kidney but not that up.
So, basically it is located in the middle and as the time goes ahead during the day as the pain becomes stronger and stronger till I am forced to take a drug to get rid of it. 100 mg of nimesulide are great and in 30' the pang is gone.
Now, it is since two days I am fine but it is also since two days I am not drinking anymore those liquid proteins.

Nothing particular but it happens always after eating, never on an empty stomach.

3
I grew up, either muscles and fat, so I think yes.

No man just what it is reported on my thread, nothing more, nothing less.
