Welcome at HCM
I have gone through your query and being your physician i completely understand your health concerns.
For how long u are suffering from it? Any other associated problem? hypertension? Any history of TB in past or exposure to TB? Are u running fever?
Zantac has got no association with the leg weakness. you need to be investigated first for probable diagnosis. if i am ur attending doctor i will get ur FBC ,
ESR, CRP, Chest Xray , Fasting
LIPID PROFILE as well as DOPPLER
ULTRASOUND of leg .In the light of these investigations i will be able to offer u any treatment.
Do engage yourself in active physical exercise along with the daily nutritional balanced diet.
Add milk and egg in ur diet along with vitamins.
Meet your doctor for proper examination and investigations
Meanwhile stay calm and use
acetaminophen to relieve pain
Get well soon
Hope your query is adequately addressed if you still have any feel free to ask
Regards
Dr Saad Sultan
