Pаtty underwent а bilаteral mastectоmy with lymph nоde remоval in the right axilla 6 months ago. She was previously a competitive rower and is very frustrated with how much muscular strength she has lost. At her first appointment, you notice erythema spanning from her right wrist to elbow. She mentions that it feels warm and slightly painful compared to her left forearm. She reports that she had been at her cabin this weekend and ended up with a lot of mosquito bites. What would be the priority in your treatment?
