I have a problem with my left index finger, i have been to 2 different doctors and still have sharp pain and swollen on side. I have been doxy for infection which did nothing, they have cut into it but found no foreign objects, also shot into it with steroids still no change. It looks like an ingrown nail. I injured it about 8-9 months ago while in the field it was swillen, red and even had some yellow discharge in the beginning. I treated it with alcohol and antibiotic cream. When I thought it was getting better, it would get this hard thick scab almost nail like on top then it peels off and starts all over again...I m left handed and bump this thing all day everyday. Its very sensitive and it s a very sharp pain. Any ideas?
