Hi Trixie - and thank you for replying so quickly. I was assigned a physical therapist who specializes in men and women who have had lymph nodes removed. She provided me with some good guidance and exercises specifically for the arm. I was pretty good doing the exercises and the discomfort was not that bad; however, right around Oct 1 it started to get worse-sharp pains. I met with the doctor on October 10th and she said that it was due to scar tissue healing and the impact on the radiation (6 weeks). At the present time it is at a pain level ranging from 3-6 and it is 24/7. I contacted the doctor on November 12th and she prescribed me 100 mg of Gabapentin 2 capsules three times a day. I have taken these and nothing happens. It is extremely difficult to sleep at night; however, I do take about an hour nap in the afternoon due to being so tired from not sleeping the night before. Not sure what a "sell spot" is - but I will look into it. Thanks again Trixie.
