On dec 19 i injected drugs using clean needles but a dirty filter. After 2 months i had extreme fatigue was itching (still am now) had headache etc... I have been tested for hiv at 10.5 weeks, 14.5 weeks and 4.5 months. I was also tested for hep c and syphillis at these times. I have also had recurring oral thrush, runny nose and crumbling lips. I feel so run down and depressed, do i need to retest for hiv/hep c? I am already immunised to hep a&b, and have tested neg for mono. This was the first time i had injected in 4 years, and prior to this i was in good health and going to college. Now i feel too sick to do anything whats up with me? Regards. worried in England
