I have had different symptoms on and off over 4 years. It began when I caught hepatitis C, Had severe reaction, was hospitalised. Subsequently my body cleared virus, but some symptoms remain. Thick, foggy, pounding headache, nausea, extreme fatigue. 12 to 18 months later it continues, and now sudden weighy loss. Lost 8 stone in last year, although I eat well and now have supplement drinks from my doctor. Also last 12 months severe skin and eyes itching. I regularly worm myself, but wonder if parasites could be cause. I also have pigment problems on my face around eyes, nose and mouth, and hair loss, my hair is very thin now. I have badly disturbed sleep. More frequent migranes, occasional sulfur burps. But.its the hair and weight loss, chronic fatigue and muscle weakness and sleep problems that are really upsetting. Please help
