What Causes Weakness In The Hand And Pain In The Wrist Joints?

Hello Doctor, Thank you for taking my question. My name is Lorna and I am very active, I workout a lot doing lots of push ups, dips, squats, lunges, weights etc. However, over the last 8 months, I have been experiencing some issues. My hands have become weak where I cannot grip things as I use to, my wrists joints hurt, even when I lift my 15lb weights or use my hands for any exercise, they hurt for the next few days. I have stopped doing those things which affect my hands, however, I work on the computer all day. Can you give me any advice, I appreciate your help.
