I thought I had Stinging Nettles and Ringworm in my hand! I didn't know what to make of my hand and it took me a long time to figure out why my left hand was so painful! I am 65 and the skin on my hands is now thin and I used a rake that was older and worn out. I didn't realize I had gotten hundreds of fiberglass splinters in my left hand! I was even treating my hand for Ringworm! At times my hand looked like I had ringworm. I tried everything on line regarding getting the Fiber glass splinters out and it took me months to get them all out!
This is what I did!
I found that soaking my hand in Epsom salt would bring out the splinters, but usually only the top of the splinter. Then I would use calamine lotion on the infected area and let it dry on my hand and the lotion would attach itself to the splinters when it was dry so I could pull or scrap them off with my finger nails! This was not the end as most of the fiber glass splinters had gone deep into my hand. I had to repeat this process every day to get the fiber glass splinters out completely!
I even went to the doctor and that didn't help. Also to help get the splinters out I used Vaseline worked into my hand followed by caster oil worked into the skin, and even vicks! The 3 oils would help work some of the splinters out! Then I would go back to the Epsom salt again and repeat the process all over again, the Epsom salt, the calamine lotion and then the oil.
It took me about 6 months to get all the splinters out! And it was HELL!
Please use gloves when working outside! My infected hand was so bad that I actually was worried that my hand would infect and I could lose my hand! Also Tinactin the fungus powder would help soothe my splinter filled hand and give it a rest. Then I would continue to treat my hand again. My hand is finally back to normal! I will never do yard work without gloves ever again!
