I took it internally 3x a day for about 3 months. A full dropper full in OJ each time. I had a sticky residue in veins of left leg left over from bad DVT and my hematologist said it was because of the clots being so bad and it would never go away. So I was left with a left leg that required elevation and compression to keep from severe swelling. The DMSO is a solvent and it cleared it out completely and healed tohe leg good as new. No swelling ever now. Leg scan confirmed the residue from Mid thigh to mid calf cleared. Unintended side effect was that i also had to wear a knee brace on right knee for any serious walking due to pain from a previous knee surgery. Haven't worn the brace since and hike my dogs 90 minutes each evening on trails.

I just ordered some at DMSOstore.com that came in yesterday but I haven't tried it yet because I'm not too thrilled about smelling like garlic, which is a body odor side effect if you take too much. So I will start at a really low dosage and see what happens.

I just used it for the first time last night. I have radial nerve palsy and it comes with mild, but constant, pain. It made a noticeable improvement in just one application so I'm going to continue.
