I feel for you. I had a similar experience in August.
I started sweating profusely, it was running through my scalp and dripping off my hair. My whole face was also running with sweat and I felt weak. I rang the surgery at about 3pm and to my astonishment, was offered an appointment at 5pm! Believe me, that NEVER happens.
I was seen by a young man, in plain clothes, who I assumed to be a GP. He didn’t examine me, but typed my symptoms into the computer.
He then told me I was suffering from hyperhidrosis, a medical type of excess sweating and prescribed a spray containing aluminium hydroxide, an antiperspirant agent to spray on my scalp.
After returning home, I started collapsing every time I tried to stand up. I rand 111 and they advised A&E immediately. There would be a really long wait for an ambulance, so I opted for a lift from my neighbour.
On arrival, my BP was 81 over nothing and pulse of 135.
Very quickly I had a drip in and admitted. To cut a long story short, I was having an internal haemorrhage. My haemaglobin had dropped from my normal 135 to66. Then I started passing dark red motions. I needed blood transfusions.
I’m still undergoing investigations, but it’s looking like the colon.
I have since found out that the eejit who prescribed anti perspirant is a physician associate.
I’m still unsure whether to take it further
