I have my first bad calcinosis eruption on my knee - not very big, about a 1/2p size, and I have been visiting the surgery to have it checked and dressed as it nearly got infected. After a couple of weeks, It is getting better but I am now having an allergic reaction to the resin on the dressings they are using. I have known for years I am allergic to fabric elastoplast. It's not an immediate reaction, it becomes unbearably itchy and comes up in weals after a couple of days of constant contact. I have an inadine patch under the dressing which is fine (the calcinosis is still weeping slightly over the course of a day but I can't actually squeeze anything out any more). It is definitely the resin on the dressing that is setting me off, it is not just round the border the whole of the inside of the dressing is sticky. Does anyone else have the same problem, and what do you use to draw a calcinosis out? As this is right on my knee joint and I am quite active - I have to climb over gates etc as part of my job as a farmer - I have to wear something that allows me to still bend my knee.
