urinary tract infection
"After being in SEVERE pain on passing (and after passing) urine saw my GP who prescribed nitrofurantoin as I'm resistant to the preferred prescribed Trimethropin. After 2 doses of 50mg same evening I woke in the night feeling like a total zombie; felt like I could barely move or breath,  like I was almost comatose. Carried on the next day tho as felt I would put this down to the infection in my body (urine dip showed something) I took every 4 hours  and feel snappy and lethargic but my main worry is the feeling of a fluttering racing heartbeat and pressure rising into my head.  I have felt a little short of breath too, as if can't quite breath in. Bladder still feeling sensitive and urgent even tho finished course earlier today."
