What can cause al your body to be in pain especially in the joints area, somtimes it makes it hard to grip things tightly. Muscles feels weak aswell?

Arthritis. Sounds like you have arthritis (joint inflammation). In general there are two types - (1) degenerative due to age and (2) inflammatory. (2) is more likely if pain worse in morning with stiffness and multiple/symmetric joints are involved. I would see your doc for full exam, blood test and xrays to differentiate.
Autoimmune problem. This sounds like an autoimmune issue. Whether it be lupus, rheumatoid arthritis or issue related condition, you need to be evaluated by your internist who can do some screening labs.
