Some people experience pain or discomfort when the catheter is inserted.

Speak to your doctor before beginning topical DMSO treatments.
DMSO may dissolve other substances, so don’t allow it to touch your clothing or other materials in its liquid form. Avoid applying DMSO to irritated areas, open wounds, or broken skin.
Be sure to let your doctor know of any other medical conditions you have, including diabetes, asthma, and liver or kidney problems, as DMSO may worsen these conditions.
