Tight muscles advice

I haven't been following a low histamine diet. I am dairy free, sugar free, gluten free, and eat very little grains and very few fruits. Iv'e looked at the diet but it cuts out the few things I can eat. I think I need help in dealing with this as I have already lost a lot of weight.

What I meant was that I need help to determine if MCAD is what I am dealing with. For example, I drink a lot of lemon water which is high in histamine. Should I or shouldn't I? Is it helping to detox or causing higher histamine levels. I am not sure if I have MCAD or a severe allergy to dead bacteria....or is that what MCAD is? I got the names of a few drs in my area that are aware of MCAD. I've read that it can take 8 months or so to get to see them. I see my dr next week and hopefully he can set up an appointment. Thanks for all the info and help.
