Oh sis I'm really sorry to hear that. May Allah give you shifa - ameen.
Is the pain in your hands worst at night? Is it accompanied by numbness/pins & needles in your fingers, pain in hand and arm? If the answer is yes, then it may be a condition called Carpal Tunnel Syndrome.
The carpal tunnel is a narrow tunnel formed by the bones and other tissues of your wrist. This tunnel protects your median nerve. The median nerve gives you feeling in your thumb, and index, middle and ring fingers. But when other tissues in the carpal tunnel, such as ligaments and tendons, get swollen or inflamed, they press against the median nerve. That pressure can make part of your hand hurt or feel numb.
However there are other reasons that may be causing this pain such as arthritis.
Now a few questions about your knees? Are your knees red or swollen or both? If Yes - do you have a fever with the swollen joints? If Yes, you may have rheumatic fever, or infection of the joints or bones. I know it's the weekend hun, but you can call out and emergency doctor.
I'm going to ask a few more q's. Soweee.
If the answer to q's above was no, then did you knees become painful/tender over some period of time? If yes, this could be due to arthritis - such as osteoarthritis.
If the pain suddenly came on and there is swelling in the back of the knee, the pain maybe due to a cyst.
God forbid it is anything serious sis. But for a proper diagnosis and of course treatment you need to a doctor, especially if your symptons are accompnied by a fever.
But whatever the diagnosis darling, please please please don't worry. Once you are diagnosed then I can recommend herbal/homeopathic treatments as well as ayaahs to help your condition inshaAllah.
If the pain in ur wrists/hands is due to Carpal Tunnel, plz don't worry as it's easily cured. Whatever you do, do not agree to surgery. Only agree to surgery as a last resort. InshaAllah you won't need it. I suffered from it a few years ago and alhumdullilah I'm completely cured now.
I pray Allah grants you shifa and that it isn't anything more serious. Ameen.
But plz, plz, see a doctor as soon as possible.
wa'alaikum aslam.
