Hello,
I have gone through history and I am sorry to hear about what and all you have gone through.
I will ask you a few questions - are you diabetic or have any signs of High blood pressure? if not checked please check it once.
As you mentioned you are heavily built and also having injuries to the ligaments of the knee this must be a disturbance occurred to the normal vasculature due to fall. As the whole body weight might have gone through it. You need to allow the healing process to occur as there will be microvasculature trauma to the small capillaries.
If you aren't diabetic I would ask you for quick icing technique as it will create a stimulation to
cold effect to the
sensory system leading to the closure of the capillaries. Which may help to reduce the swelling and pain.
Also, you can request the physician about the medicinal ointment for the healing as brand name varies from country to country I would not be able to guess which is available in your country.
Also, try keeping the limb over the pillow and immobilized so the healing of capillaries takes place.
For you
ligament injury you need to check with the orthopedist as, if it has gone to full tear then you should be following the guidance of the orthopedist.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Jay Indravadan Patel, Physical Therapist or Physiotherapist
