My doctor is insistent that Imunovir is the only way to get my killer cell activity to rise from 8%. I have yet to find anyone who has really been successful with it. There seem to be few studies on it. I am extremely chemically sensitive and reacted badly to inosine from the health food store. My worst symptom is dizziness and i read that Imunovir can increase that. Plus, I have interstitial cystitis and the whole uric acid increase concerns me. And I have heard about wicked migraines, and already suffer from those. It seems to me that stress reduction can help increase the activity. And there must be other alternatives. I cannot believe there are no choices. My doctor refuses to retest my killer cells unless I take the medicine, but I think it may be improved due to other things I am doing. I'm really struggling with this so if anyone has some insight, I would love to hear it. Thanks!
