Fatigue etc illness

I had my appendix out in february and then had 2 more operations after due to iodine being left in my belly and the sepsis. Spent 2 weeks in hospital and quite a few complications since. But almost 6 months on Im still suffering from a few symtoms. I have a few ok days then BOOM,I go all pale and gaunt and can barely walk Im that fatigued. My last visit to the docs my bloods show my white blood cells are 2.1 and gradually dropping and platelets are low. I suffer from dizziness quite a lot also. One other niggling problem is, the last 6 months since last op, I havent been able to lie or lean on my left side,if I do i get excurciating pain in my right lower rib,top of stomach area and pain goes up into neck and shoulder. Ive had an ultrasound and said all is ok. Its so frustrating has I know something isnt right. When hoovering for example,when pushing out i can feel a clicking kind of thing in the same area. Any ideas whats going on in my body as my doctor doesnt seem to know. Im waiting an appointment to see an haematologist also. Thank you.

Thank you for the reply. Since my last dental work there is food that gets stuck in my the roof of my mouth and I have to floss it out but having the urge to go deep to make my gums bleed. Also any ideas on how to get rid of parasites if thats what I have. The hospital I was in for 2 weeks was absolutely disgusting. Poo up walks blood in sinks and showers so i guess this is also possible. Thank you

Hard to find has many dont except it as an illness by the looks of it. I had a broken tooth and they filled it. But now I get food trapped above the tooth and when food has been in there a while I have to use the floss and be extra rough to make it bleed to relieve pressure. Im back at dentist a week monday wven tho my doc said I shouldnt go as my white blood count is so low. Thanks.
