Diverticulam & Subcentrimetric lymph nod

I m suffering from discomfort and uneasyness since last 45 days.. had done many blood reports but all came to be normal. but then i was advised to go for abdominal CT scan and then the results came up with 3 conclusion; 1.heptomegally with fat infiltration ( Grade 1) 2.few diverticuli arising from the cacum. No evident changed in diverticuli/perforation. 3.few subcentric lymph nodes in the mesenteric areapredominantely in right Iilac region. Apart from this i also have Diabetes and High Blood Pressure, both are perfectly in control and never had any discomfort because of  these condition in past. But now as soon as after having my meal my condition gets detoriated.and i feel high heart rate, light headedness and i feel that i will collapse. All my Ecg, Echo, and Tmt came out to be normal. I m really tensed because of this and want a permanent or atleast relieving treatment of this. Medication:- Nexpro IT - 1 in a day Telpress 40 for bp Cefolac 200 ;  0-1-1( since last two days)
