i had AMS 700 LGX with MS pump in about 3 weeks ago.

Doctor said that i can try to cycling everyday.

but last night i tried to pump it. The pump was as hard as a rock; I used a lot of force, but I can't pump it.

Has anyone else had the same experience? Is it because I haven't used enough force? Or is there something wrong with my pressing technique? Will this pump stay this hard in the future?
