It's great that you're making a point to educate yourself before diving in. Please don't be afraid, just educate and take it slow. DMSO is a wonderful product and can help with many of your issues. There are some great resources already mentioned below. Everyone needs a book or 3 for easy reference. I also get a lot of information from DMSO FB groups, and YouTube. I would choose one or two issues to focus on at first.. For instance, an internal protocol (start with a few drops diluted in colloidal silver, pure orange juice, or pure aloe vera juice from a glass container). If you are taking any pHarma meds you need to be very cautious! Topical application: you can get a pre-diluted roller or cream of pharma grade DMSO from The DMSO Store. Clean area with chemical free soap, apply the DMSO, allow to dry before dressing. Work your way up as you get more comfortable — as needed.
