Blisters and more

More blisters on my sole. Same area. Right leg. I think my walking posture must be somthing wrong, becoz i am wearing very comfortable shoes. How can i get blisters. And they are cluster together same place. Growing bigger and i can feel the fluid inside....painful when i walk. Sianz......and plus my 100 days cough, more sianz.... But i went to see tcm just now, got some medicine. Hopefully can speed up the healing process of the cough.... 100 days is too long....i still have 2 tuition tomolo. Today i went bb fair at expo. With ah lian and her hubby. She bought quite alot of things. Actually i think too early to buy coz can buy them when she is six mths. That will be a better time. Normally i buy in third trimester. Nearer to delivery day.but she scare she no time to buy, so prefer to buy most of the things now.
