rs910 How's your immune system? I had every one of the symptoms you posted. Costochondritis was so bad my chest felt like it was being crushed. I also had a failing biome system so the chest pain was complicated due to a failing digestive system. Even my liver was impacted. At the same time I had headaches and a major drainage from my sphenoid sinus that was causing loss of taste, smell and an enlarged tongue that burned all the time. The T-Cell blood test revealed I had a failing immune system; specifically my body had not been making any CD8 cells and they are the 'debris' removers for dead cells. Since I had no CD8 cells, the spike protein fragments were not being removed from my body, but instead being deposited in locations throughout my body. I became a storage container for spike protein fragments and they were poisoning me. Micro surgery of the nasal passages (sphenoid and malefactors) found spike protein fragments had clogged up the passages and the yellow drainage was filled with spike fragments which were damaging my tongue and my intestines. The pain of costochondritis combined with loss of taste and smell and a 'yellow coated tongue' were the very first indicators of LC and they appeared within 1 month of contracting Covid D (March 2023). It wasn't until 2025 that the micro surgery was the first pain relief solution. Costochondritis stopped within 2 months of the surgery. In the end, all my LC symptoms were related to damaged and dysfunctional T-Cells from the spike proteins.

Germany has taken the lead on 2 blood tests resulting from studies in 2023-25 of individual Long Covid patients reported symptoms. Those results were placed on a graph. Here is the medical open access journal of record for this report. Numbers represent 'humans' in the study: https://www.mdpi.com/2076-393X/12/7/790
