My husband Had went chemo for his Hodgkin lymphoma 3 years ago, unfortunately he relapsed within 12 months. But with only a small lump in his neck appearing, followed but a few more,no B symptoms though. (He never had B symptoms the first time and his cancer was stage 3 with a large lymph node approx 14cmx5cm.) he's had a few check ups since then for reassurance but he's been put on watch and wait as his consultant is happy his cancer is slow growing. 
 

however, he's now Ill all the time! Currently having severe pain in his stomach which our gp is invistigaying, also suffering with headache (a severe migraine tonight resulting in vomiting). He just seems so unwell all the time, which is so unlike him pre-chemo. Could this be down to the 6 rounds of chemo? Or should we be seeing his constant to check? I don't know with watch and wait when you actually need to ring and when to just leave it play out,  as we understand he can be unwell just like a normal person. Anyone else on watch-and-wait? Or similar? 
 

thansk for any help
