Detailed Answer:
Hello,XXXX
Thanks for asking HCM.
I am Dr Rakesh Sharma replying your query.
All your other symptoms indicate a severe reaction of the drug.
As allergic reaction is sort of inflammatory reaction it can cause swelling of glands as well.
At the same time you should also keep in mind that what ever infection you have may not be sensitive to bactrim if are still having symptoms, the infection may also involve lymph nodes as well.
Start anti allergy treatment as soon as possible under strict medical supervision as if uncontrolled may become an emergency.
I again want to warn you against anaphylaxis,Please immediately seek medical attention.
If you have any query do not hesitate in asking.
Best Wishes.
