<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have Foliculor non-hogkins lymphoma in the left abdomen 6-7 cm, for which I am treating with Rituxan infusion but now I have swelling under my left arm, left peck, lower abdomen, inner thighs on both legs. The tumor seems to be shrinking in the last CT scan with contrast. I am also experiencing itchy burning eyes 247, raspy voice, blurred vision, ringing ears. I have ruled out allergies though testing with allergist and ENT. Your thoughts? Accept what terms?  <response>: Hello, Welcome to Ask a doctor services. I have read your query. It is good to know that the tumor is shrinking. Swelling that you are experiencing in your hands feet is a side effect of Rituxan. You need to report without delay to your treating PCP, you need to be examined medications need to be monitored or altered. You should keep your PCP informed about any other medications you are taking. Stay away from addictions. Hope I have answered your query. Let me know if I can assist you further.
