Anyone taking antimalarial drugs to prevent malaria who develops a fever or flu-like symptoms while taking the medicine or within 2-3 months after traveling to an area where malaria is common should call a physician immediately.
Treatment of knee pain depends on the cause of the knee pain. If you have been working on your knees all day then potentially rest and anti-inflammatories such as ibuprofen can help. If the cause is trauma and there is possible joint damage then you should seek medical attention.
Initially, you should treat the knee injury with conservative techniques including rest, ice, compression, and elevation (RICE): 1  Rest your knee, and use crutches to avoid any weight bearing on the joint. Avoid any activities that worsen your knee pain. 2  Ice your knee every three to four hours for 30 minutes.
