aches in shoulders, upper arms and elbows

I’ve been taking 2.5 mg Bisoprolol in mornings for 10 years. 4 years ago I had a CABG x 3.
They increased the dosage to 5 mg as I had a AF episode, also apixiban was added. I don’t take apixiban any more.
I take 2.5mg Bisoprolol, 50mg Potassium Losartan, 2.5 mg indapamide, 75mg aspirinat08:00 and 50mg Potassium Losartan, 2.5mg Bisoprolol Fumarate at20:00. I’ve ditched the statins.
However since my increase in Bisoprolol I started to get very achy shoulders. I never thought it had anything to do with Bisoprolol.?..
Recently I’ve been on a low carb diet and my BP has dropped enough to stop taking one of my BP meds. I started decreasing my Losartan and nothing much happened so I though I’ll decrease my Bisoprolol.
After about 6 hours I noticed my aches and pains in my arms have gone. My runny nose and ringing in ears have also diminished. WTF!
Has anybody had similar results??

The ringing in the ears is awful! l’m only on a sliver now but everytime l try to stop my heart rate jumps if i get up and walk to the kitchen. Dizzy and morning anxiety which l never had before starting this tablet. My Cardiologist said to wean down slowly as im having withdrawals due to being sensitive to Bisoprolol. :frowning:
