I'll check all my bloodwork from the rheumatologist/endocrinologist for the level you mentioned. I have taken Augmentin (Amoxicillin) 875 for years for sinus infections...it's not working now for them. Z-Pack most of the time works for the asthmatic bronchitis & pneumonia, but, not for a sinus infection. Since I have long Covid, I am getting these infections (Sinus/Asthmatic Bronchitis/Pneumonia) more frequently. The Levaquin 750 for 10 days worked great and then I rebounded 3 weeks later and just finished the Levaquin 500 for 5 days. I cannot take Doxycycline as it tears up my stomach. I'm glad that one works for you. Cromalyn nasal spray is over the counter and works differently than the other nasal sprays. I felt I needed a break from the steroid sprays and did my homework and Cromalyn was recommended for recurrent sinusitis/allergies. I also took Singulair for 5 months and I couldn't tell it helped as I kept getting infected, so I quit taking it. The Azesteline (Sp?)
spray for drainage helps, but, is not a cureall. I was put back on Flonase and told I could use all 3 sprays and so I am. I also irrigate my sinuses with the NeilMed Sinus rinse which comes with saline packets (I only use 1/8 of a packet as it burns terribly) every day to try and keep the bacteria down. I think Covid did a number on my immune system (hence, a new autoimmune disease they can't diagnose yet) and chronic asthmatic bronchitis & sinus infections and pneumonia again. I never had pneumonia until I had Covid last year. I only use Afrin if I have a lot of sinus pressure with my teeth hurting and facial pressure. Sometimes, it will help greatly. I cannot take decongestants orally and Afrin is a 12 hour spray decongestant. I only use it 3 days. I also get in the shower and let the hot water beat on my face to help with sinus pressure. I use the BedBuddy heat packs on my face as well. Vicks puts out a steamer that is great as well. It helps open up my head when I am all clogged up. You insert a Vicks strip and put your face in the molded plastic. I used this a lot when I had Covid. It does help. I'm wondering if you have a pocket of infection in your sinus cavity that is just not clearing up. Have you had a ultrasound or MRI done of your sinus recently? When I had my old ENT doctor for many year (he passed away) he would call in Neosporin irrigation from a compounding pharmacy and I would irrigate my sinuses with that and it worked great and cleared me up. I haven't find an ENT doctor that will culture my sinus or call the Neosporin Solution in. I think I repeated myself on some things I told you previously....sorry about that. Praying you get relief from this. By that way, have you had Covid? It can cause skin issues is why I ask. I have never had ezecema in my life until Covid. I have it in both ears and just got a prescription from the Dermatologist for it. I ask because Covid can cause skin issues and you mentioned your skin issues. God Bless You. You have been through so much. Hugs & Prayers....
