Can anyone help with these wierd problems - neck cracks/grinds pain at base of skull/top of spine/shoulders/chest, sometimes feeling of congestion in top half of body, dizziness, headaches sharp stabbing pains, stabbing pains in upper arm muscles, occasional blurry vision, pain in shoulder blades. Blisters on left foot! Occasional loss of sense of smell. Nausea. I don,t have all of these things everyday {apart from neck pain] they come and go, but I have them all at once sometimes, I suppose you would call it flare-ups, but flare-ups of what. Any help would be appreciated. Does anyone think it might be connected to menstral cycle somehow, or menopause. I have been searching for answers for a couple of years!
