Sorry its a long read

I had a misscariage in jan at 11wks. I hadnt been feeling to well and had been under alot of stress since i found out i was preg back in november a day after i had a car crash and wrote my car off. Come december i was admitted in to hosp with food poising and then mcd a month later in january. Now when i got my bloods taken in the hosp when had my mc they were showing extreme high wbc at 45. 2days later theyd gone down to 16 with antiobiotics and have never had them done since. Now according to google high wbc can be signs of cancers etc. 3wks ago i felt a lump like thing on chest like were my rib cage bone 2 (that feels raised to) cartlidge joint bit is connecting to the sternem would be. Obvs google gave me answers of cancer.. docs said not worried and could be just the way my rib bit is and cos iv lost weight i can feel it more but has transferd me for a us to put my mind at rest. Now i do suffer from psoriasis so im wondering if that could cause a higher wbc along with stress and mc thats why it was high last month. Also my mam has psioratica arthuritis, which that causes joint inflamtion so was wondering maybe if that was a poss cause to why rib bit feels like that? 🤷‍♀️ im such a worrya and worry the docs can get it wrong and with the luck iv been having lately. And worry it was to be cancer and thats what caused me to mc 😭
