Dr. Andrew Weil is a well respected Doctor in the medical community that blends both conventional and alternative medicine. Here he talks about the use of dmso for frozen shoulder pain syndrome.
Word of caution: Be very careful using dmso as it can burn if used improperly.Keep it out of the eyes etc…
Very effective for frozen shoulder,but it needs to be used with informed caution and respect.
A great bit of info from the famous Dr. Weil
Before resorting to such drastic measures, I would try acupuncture and osteopathic manipulation; both can be helpful, and both are safer than more invasive measures. I also recommend trying DMSO (dimethyl sulfoxide) topically. You can buy it at your health food store or on the Internet. It penetrates the skin and promotes healing of pockets of inflammation. Make a 70 percent solution of DMSO by diluting a 100 percent solution with distilled water and apply it to the shoulder with absorbent cotton. Let it dry. Apply the solution three times a day for three days. If you don’t see any improvement, stop using it. If you do notice improvement, cut back to twice a day for three more days, then once a day for a final three days. After that your body can continue healing on its own.
-ps make sure to clean the skin fully before using it as the dmso will transport anything on the skin to the inside
