Hi,
Noted the history about your Mother having had fractured
tibia, surgery to put in nail 15 days ago, got the swelling and discoloration after standing with crutches, you made her lie down and the color came back to normal.
This is quite uncommon finding.
There will be some time to develop edema and discoloration but your Mother's case this appeared fast.
his can be really a problem related to her venous system and needs to be confirmed or ruled out like
Varicose veins. venous blockage due to DVT and so on.
Hence I would advise you the following:
Yes, take her to the Doctor/Hospital immediately.
Have clinical evaluation.
Ultrasound with color doppler of the affected limb is a must.
Relevant tests of blood.
Further management as per the cause found.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT and General Surgeon
