Hello and welcome to HCM,
The injury to the wrist has not caused any fracture of break in bone but it has led to
soft tissue injury.
Hard lumps on top of hands are probably due to soft tissue swelling and reactive
fibrosis.
Numbness in little finger is suggestive of injury to the nerve supplying the little finger.
Nerve injuries commonly accompany soft tissue injuries.
Pain and
stiffness in the elbow are again due to soft tissue injuries.
Thus, all symptoms experienced by you are sequelae of soft tissue injury to upper limb.
Nerve injuries usually recover spontaneously but a clinical assessment by an orthopedician is required to assess the type and extent of injury.
The pain and stiffness needs to be managed by rest, hot fomentation, pain killer and
muscle relaxant.
The stiffness may take longer to disappear and may require
physiotherapy.
You need to consult an orthopedician for clinical assessment, prescription of medication and to follow up.
Thanks and take care
Dr Shailja Puri
