"dermatologist put me on bactrim ds, to be taken twice a day with food. no side effects in the first few days and did a good job at clearing up my face. currently i am on the 9th day and experiencing severe side effects. fever, chills, extreme joint pain, muscle weakness and overall sluggishness. also experiencing difficulty breathing, a tight chest, headache, and dizziness to the point of almost falling over, for no reason. the most severe of the side effects is the joint paint. can hardly take a step on my right leg and cannot lift anything with my right arm. bactrim does it&#039;s job however at the expense of your health. please do your research before starting this drug!"
