Dr. Ryne: after prostate surgery I developed a blister that became a deep sore very near the site of the indwelling catheter. I suspect a reaction to the adhesive in the patch used to hold the catheter in place. I saw an ER physician re this sore; he thought it was beginning to heal (two weeks duration; it is a bit better now) and prescribed clindamycin for seven days as a protective measure in the event the sore was related to a staph or Mersa infection (but not c. difficile, unfortunately). I have take the antibiotic for six of the seven days and have become increasingly convinced that it is negatively interfering with the healing of the prostate after surgery (the post-surgical symptoms are intensifying instead of abating). Today I noticed for the first time that my skin has become quite sensitive (especially back and arms) and it seems to come under the heading of a severe reaction. Would you advise stopping the clindamycin, or would you advise taking the last four (five actually) doses to finish the course of treatment? I would appreciate any assistance you might feel able to give. Thank you Phillip Bamman Santa Fe, New Mexico
