Hi. I was diagnosed in 2009 with the very rare Yellow Nail Syndrome which comprises sinusitis, lymphoedema and bronchiectasis. Since then, I have had infections of the sinus and chest requiring antibiotics 3-4 times a year. Until this year, I took 500mh Amoxycillin for 14 days but in April this year, I developed a really itchy rash after 2 capsules and the GP changed them to Doxycycline 200mg for 14 days. I started with a chest infection 3 weeks ago and my GP sent off a sputum sample on Monday this week. I am awaiting my GP to prescribe the relevant antibiotics but they seem uncertain about which ones to give me. I am going to ask for doxycycline until a decision is made but will also ask for a referral to a bronchiectasis specialist now rather than my general respiratory consultant.
