I have an 8x6x6 colloid cyst. I am suffering dizziness which is affecting my balance. I also have been withdrawing from Effexor, haven't had 37.5mm for a week now, after 2 weeks of one every 2 days, I'm concerned about Hydro, but I don't know if I'm confusing this with the withdrawl. Both arms are aching and heavy when reaching upwards, my ears seem blocked and my neck is aching, as well as right underarm is really sore to touch...
