Lots of good advice here already. I was recently put on new/different meds because of new symptoms in mr back/neck vs rge crps in my ankle. I did a bing search and found drugs.com. You can check drug interactions there so if it's a reaction between meds vs just a side effect of a med you may be able to see something like that on there. I am sure there are other sites to do this on...this was just one that I used in the last week that I found helpful.
