in alot of pain

i have been seeing alot of docs since monday. they still have not really found a cause for the fever. one doc will say its an infection, another its a fungal infection, and then another will come and say it because of the chemo which made the white cells count low. the white cells are needed to fight infection. they just dont know so they have put me on alot and i mean alot of antibiotics. the antibiotics they have put me on are also very strong. they did decrease my fever for a day but then again i got a fever and this time with the fever i also got these little swellings on my lower legs. yesterday the swellings were small and not that painfull but today they have become so painfull and red. i can not walk properly now as when i put weight on my legs they pain alot. the doc said they might be an sideeffect of the antibiotics they are giving me. they also said it could be an infection. they have to do a biopsy of the swellings and that cant be done till monday. so they cant treat the swellings till then. i will just have to bear the pain till monday.
