What Causes Sharp Pain Behind Knee Along With Pericarditis?

Can be muscle spasm.
Detailed Answer:
Hello,
Thanks for posting your query.
The shock like pain at the back of knee can be due to a nerve root compression at the level of lower spine or a sudden muscle spasm in the area. This is not likely to be related to pericarditis.
Sometimes, it can be due to dehydration, muscle fatigue or electrolyte abnormalities. It is better to drink sufficient fluid and also see that your intake of electrolytes (sodium, potassium, magnesium ) is sufficient. You can drink Oralyte for this.
Do start taking Vitamin B complex supplements also and see if it helps.
I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Wishing you good health.
Regards.
