Hello
First I will advise to do x ray and rule out any unicortical fracture in your knuckle.
There is possibility of injury to ligament of metacarpal or phalange joint.
If you are having swelling and pain you can strap your finger to get proper rest to joint.And apply crepe bandage for support and compression.
Use ice packs to reduce swelling, inflammation and pain.
Physiotherapy with
ultrasound and Tens will help you,
For early healing you can take Tab celin [vit C] and antioxidant with anti-inflammatory [Tab enzomac plus ].
If there is no relief them you may need to do MRI.
Rheumatoid arthritis may involve small joints and early morning stiffness in joints, do you have such complain?
When such patients come to our hospital I advise them
blood test like RA factor, ACCP, ESR,
complete blood count, HLA B27
