lots of people tend to warm joints etc. when they hurt or are stiff - this may prove cuddly and cared for but if it is inflamation causing the problem - warm brings more blood, more fluid and in pure logic more inflamation! Great for healing cuts, abrasion etc.
Try a pack of peas out of the fridge - that will cool and may help!
When I googled Sombra I didn't realize it comes in so many forms. I use the one that is in the jar. On the site I looked on 8 oz. was 13.99 which is just about what I pay. It's really great stuff and I hope it works for you.
I don't think you should be afraid to give your Dr. the information from Dr. Lamm. That is sort of like giving your local chef a tip from Julia Child. I told my surgeon about the homeopathic advise I had gotten and he was very willing to listen and my local uro told me he would work with the surgeon and do as much or as little as Dr. Laudone wanted him to do. Go for it. I have found that even with the skill of all the doctors you have to be your own advocate and hopefully he will "learn" from your experience so some patient who comes along in the future will not have to go through what you have gone through.
I don't know if you have read my post about Sombra. I know you can buy it on line. Just google the word Sombra. It is a homeopathic cream and it works like a miracle on the arthritis in my hands, ankles, knees and feet. It's especially bad in my toes. Anyway, it smells great, like citrus. Maybe you could try a small jar of it and see how it works. Also, the doctor told me to take glucosamine with MSM every day and when I had to go off all vitamins before surgery I noticed the difference and it is better now that I am back on it. Arthritis is no fun.
