Hello,
As you had a trauma of knee joint while playing soccer, the following might be few probable causes of your pain:
1) Meniscal tear
2) Collateral ligament injury
3) Patellar fracture
4)
Hemarthrosis of blood in the joint.
5) Sinovitis or inflammation of membrane lining the joint
6) Bursitis
To those who come to my clinic with similar injury, I would recommend the following:
1) X-ray of knee joint
2) If it is inconclusive,
MRI of knee joint is to be done to spot the accurate diagnosis and treat accordingly.
3) For the time being, to reduce pain, you can go with OTC pain medications like tab.
Ibuprofen and
Naproxen.
Please do consult an orthopedist for further evaluation. You can have your period up to 10 days before or after your actual date. So you don't need to worry as the delay is very much normal. You can wait for 1 more week and then you can go for urine
pregnancy test.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Pallavi M., Anesthesiologist
