Hi, a few weeks ago I mentioned to GP rapid heart rate and palpitations plus swelling in lower legs so because I was about to start K, we decided an ECG would be a good idea plus he checked various bloods, blood pressure, pulse, circulation etc. BP was and always has been, totally normal. I started K a few days after the ECG which was normal. Am now 6 weeks past first dose and have done 4 shots in total. This week have felt light headed and headachey plus some chest tension. Put it down to vertigo and MS hug both of which I get a lot. Went for flu jab today and got nurse to check my BP - very high!! Have to check daily for 7 days and report back to Docs. Has anyone else on Kesimpta had this? Am wondering if it is a side effect?
