Hi,
Noted your history and understood the concerns.
The most common cause I can think about the pain in wrist and forearm within a few minutes after using right arm for wrenching followed by slight purple and red area in hand can be as follows:
Acute muscle tear due to excessive force and bleeding can cause such problems.
This can be diagnosed by the following ways:
Urgent consultation of a Doctor, preferably an Orthopedic Surgeon for clinical evaluation, examination and investigations such as
Ultrasonography or still better the
MRI of the affected area can get you the proper diagnosis.
Till then use sling and do not use the affected limb at all.
Try to elevate the limb above heart level in laying down position.
Take an anti-inflammatory medication like
Ibuprofen if it suits you.
Further management as per the findings.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant, ENT & General Surgeon
