Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain pain and swelling in knee can be due to causes like Traumatic
injury to knee, Arthritis,
Bursitis,Gout,
Pseudogout,
Rheumatoid Arthritis, Baker's cyst etc..
I would suggest you to consult an Orthopedician and get evaluated and a thorough clinical evaluation and investigations like x-ray, MRI Scan, blood tests etc can help in diagnosis and treatment can be planned accordingly..
You can be advised to take anti-inflammatry painkillers like
Ibuprofen for pain relief and topical application of
analgesic ointment like
Voveran..
You can be advised to follow the most common technique that is R.I.C.E that is REST which means refrain from workout, sports, vigorous walking, long hours standing etc..
ICE: Do cool compresses over the joint for fifteen to twenty minutes as it will help in reducing swelling..
COMPRESSION: Cover the knee using a knee cap or crape bandage as it provides support as well as reduce swelling..
ELEVATION:Put pillows under your legs while lying down and raise it from the level of body..
By these techniques the swelling will reduce in 3 to 4 days and in case if there is no improvement treatments like Arthrocentesis or surgery can be advised depending upon the cause..
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora.
