Hello,
Thank you for posting your medical query to DoctorSpring.com
So 1 week prior you feel on your elbow and since then have pain located in your wrist. It doesnt appear from your description that there is a fracture since you would have been in excruciating pain, the hand would be too painful for even minor movement and there would be obvious bruising and swelling.
I would recommend that you take an X-Ray to rule out the possibility of a dislocation. If the bones forming the elbow joint are dislocated they could produce some of the symptoms you described or you may have also landed on your wrist and not realised it. Kindly reply with an upload of an X-Ray which will guide further management. In the meanwhile, I would advise a crepe bandage and using a topical muscle rub cream. You can buy any topical analgesic pain relief cream which is available of the counter
Hope this helps
