Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain you have symptoms of pain in knee which exaggerates on different movements like sitting on feet, jumping etc..
It can be due to a number of causes like Traumatic injuries,Tendonitis, Bursitis, ligament or
meniscus tears,
Osteoarthritis,Iiliotibial band syndrome etc..
I would suggest you to consult an Orthopedician and get evaluated and a thorough clinical evaluation and investigations like x ray, MRI scan or
blood test can help in diagnosis and treatment can be planned accordingly..
You can be advised to take anti-inflammatory painkiller like Ibuprofen, muscle relaxants like Chlorzoxasone.
You can be advised to do cool compresses over the knee..
Apply an analgesic ointment and put a knee cap over it..
Elevate your leg while lying down..
You should also avoid excessive exertion and also try to loose weight if you are overweight.
You can be advised
physiotherapy under supervision of a trained Physiotherapist..
In case of no resolution treatments like
Arthroscopy can be advised..
Hope this information helps..
Thanks and regards.
