My brother put some DMSO gel (70% dmso, 30% aloe vera) on his shoulders and lower part of neck because he had muscle pain/soreness in that area, and it caused skin redness/irritation for a few hours, although it did diminish the muscle soreness as well. We're testing to see what it might be now - he's going to try putting some on legs/arms which should be less sensitive to see if anything happens then. If it doesn't I'll assume it was because the neck is more sensitive, and I know the recommendation is 50% dmso solution for neck/face but he didn't have any pure dmso so he just used the gel he bought. If the irritation happens on arms/legs, we'll try pure dmso in solution with distilled water to see if it's the aloe vera that caused the irritation. I know someone reported earlier in this thread that mixing dmso with oils can cause a similar burning irritation, so perhaps mixing it with aloe vera could have a similar effect (although this is how it was sold). Anyway, just wanted to report that experience, and if anyone has any ideas, they're most welcome.
Also, my grandma has rheumatoid arthritis that made her legs swell up and hurt continuously, and I had her apply the same DMSO gel, and after about 2-3 days of applying it once a day, the swelling was 90% gone, and I think within 4-5 days it was 100% gone, and she said the pain diminished as well. She was so happy and surprised by the results that she's now on the ultra simple diet for a few weeks now and feels amazing and lost tons of weight! She doesn't just lay on the couch anymore in pain and with no energy - she's a whole new person, walking around and being active and enjoying life! And she actually takes me seriously when I say that I know things that can really help her. Until trying the DMSO, she only took her doctor seriously, and since the doctor was no use, she didn't think it's possible I'd be able to help her either because I'm no doctor - but not anymore! This also had a very powerful effect on the rest of my family, who are all about to go on this diet as well, and are actually starting to take my suggestions seriously too, so proof positive goes a long way. So we have a positive result here and a weird result with my brother. On the bright side with him, he's been on the ultra simple diet for a few months now, and I'm proud! :) The next step for both of us is heavy metal detox, but we have a few more months of more basic dieting first before that happens.
Finally, I was in a small car accident recently where I was rear-ended and my girlfriend got whiplash as a result, so I've ordered some pure liquid dmso and medical tape, and will apply both and report the results. I'll have her take a teaspoon in a glass of distilled water once a week, and also mix 50% dmso and 50% water and apply that to her neck/shoulders/back where the pain is, and then wash those areas after about 30/60 mins and then apply the medical tape for as long as it sticks, and then rinse and repeat, etc. And of course, I'll report on the results.
. I didn't say anything when he mentioned a rotten smell and was a little embarrassed. I could just take it after doing grocery runs, but my mom said that I smell very bad.
