HODGEKINS-A FEW WEE QUERIES FOR EVERYONE

hi all well mum had her 5th treatment last week for hodgekins and i was just wanting to find out if how she is feeling is normal really , and if anyone can relate to it, well, she went for a lung function test two weeks ago and thre results were fairly good, she was told she had slightly improved which was good because an improvement in the first 6 to 8 weeks is usually very rare. so that was good news. she went for pet scan a few days larter and the doctor said to her they shud have the results in a few days and that if the chemo wasnt working and she needed stronger they would contact her and get her in to talk it over, but nobody has been in contact, im not sure if this is good or bad but im guessing if anything had gotten worse thy would have been eager to get her in, and i guess her lung function may not have improved as much however they have contacted her for another lung function test, were not sure why, we think maybe its just routine to see if shes still improving , does anyone know how often these tests are usually done? only other thing we can think of is that she is waiting on the doc filling in her benefit forms and maybe they need to do one for that purpose. my mum is worried they may have founf cancer in her lungs but i am doubtful, i dont think the test results would have improved if this was the case?and surely they would have phoned to get her in instead of sending her a letter? anyway shes doing not too bad , she feels rough a few days after chemo but then picks up and gets up and about but feels frustrated because she gets knackered really quickly! does anyone else feel this way? she seems to look a lot better, but she still has this skin itching thing, which ive read can continue beacuse the chemo is blocking her lymph glands for the minute, she is nowhere half as bad with the itching now though. does anyone else have anything similar? any thoughts people? thanks kerri x x x
