hello i have very bad pain in both knees for four weeks is it possible side affects from being prescribed lansoprazole three months ago also bad fevers now and then
Hello. I'm Dr. Phil, licensed and practicing internist. Excellent service is my goal.
Yes, it could be an allergy to the medicine or a reaction
However, fevers and joint pain points to infection or inflammation
I think you need some tests done
To check for infection, get a CBC (complete blood count) and blood cultures.
to check for inflammation, get an ANA, rheumatoid factor, sed rate, CRP and a CCP level.
These are all blood tests.
A medicine reaction is possible but I am leaning more towards inflammation or infection
