Hello,
Most probable reasons for your pain in the back of knee might be the following:
1) Leg cramps
2) Patellar tendonitis
3) Hamstrings injury
4) Baker's cyst
5) Calf strain
6) Meniscal tear
7)
Posterior cruciate ligament injury
8) Arthritis
Mostly your pain is due to hamstrings strain. The following treatment is recommended:
1) Pain relief medication like NSAIDs
ibuprofen or
Naproxen to be taken twice daily for 7 days
2) You can use tab. Pantop 40 mg once daily before food to prevent gastric irritation caused by pain medication
3) If you can't use NSAIDs like in kidney failure and bleeding disorders, you can use opioids like
Hydrocodone,
Oxycodone and Tramadol instead of Ibuprofen
4) If your pain doesn't come down in 4-5 days, you need to consult an orthopedic specialist
You may require investigations like X-ray of knee joint, MRI of knee joint and back side.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Pallavi M., Anesthesiologist
