I have had a fluid filled vesicle on my third toe for one and a half years. I showed it to my chiropodist and GP. Both told me to leave it alone if it does not bother me. Meanwhile it has continued to grow from a tiny pea to a big pea size. Today after a shower I noticed a viscose sticky clear liquid oozing out of the centre. On applying pressure more and more sticky clear liquid came out of a tiny sized pin prick with the loose sack of skin largely intact. I poured Betadine over it and left it open to air. 2 hours later and the loose sack of skin is beginning to fill again. What and why is it? What should I do? With Best Thanks
