I have pretty much constant knee pain with feelings of swelling sometimes but my knee never looks visibly swollen. It is totally impossible to ever kneel or crawl on my knees as it feels like someone is stabbing a knife into my knee if I even try. I am on a mild Nsaid Rx via my Dr but my question is it arthritis? Five years ago I could run now the best I can do is a fast walk or a slight jog. If I palpitate my one knee when I am sitting I can feel an slight grinding / popping with my fingertips. Thank you.
Hello, What is your age? Your symptoms are suggesting the possibility of arthritis of the knee. It can be inflammatory arthritis or degenerative arthritis if you are above 45 years.  Diagnosis cab is confirmed by X-ray of involved knee anteroposterior and lateral views. Please get it done from radiology center nearby you.  Meanwhile, avoid sitting crossed leg position and stair climbing.  Tab diclofenac can be taken for pain relief. You need to visit Orthopedic surgeon with X-ray report for detailed clinical examination.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
