Hi Deb,
You mentioned in one of your posts about DMSO. This will cause your pain levels do go up at first.
Also, some people experience an increase in pain for the first couple of days of use, and it then improves pain. If given in large dose IV, it can rarely cause hemolyis (breakdown of red blood cells).
Here is a article on DMSO that is well worth reading.

I was on IV's for about a year 2-3 times a week. My Doc told me it was hard on my veins any more than that. He had me take a very low dose orally at times as well. Which I am considering taking the oral again.
The SX I had for about a month was a increase in pain. In my case it was the neuro. & muscular toxicity coming from my body. I would also get some rough headaches at times. Hugs, Roz
